X=2 y=3 is a solution of linear equation
X=2 y=3 is a solution of linear equation-What we need to do, then, is graph the solution set of the linear equality in two variables x y <In mathematics, a linear equation is an equation that may be put in the form a 1 x 1 ⋯ a n x n b = 0 , {\displaystyle a_{1}x_{1}\cdots a_{n}x_{n}b=0,} where x 1 , , x n {\displaystyle x_{1},\ldots ,x_{n}} are the variables (or unknowns ), and b , a 1 , , a n {\displaystyle b,a_{1},\ldots ,a_{n}} are the coefficients , which are often real numbers
Write a pair of linear equations which has the unique solution x = – 1 and y = 3 asked in Class X Maths by saurav24 Expert ( 14k points) pair of linear equations inLinear equations are those equations that are of the first order These equations are defined for lines in the coordinate system Linear equations are also firstdegree equations as it has the highest exponent of variables as 1 Examples 2x – 3 = 0, 2y = 8 m 1 = 0, x/2 = 3 x4x 10y = –22 2x – y = 1 ;
When we plot the graph of the given equation, we find that both the lines intersect at the point (3, 5) So, x = 3,y = 5 is the required solution of the pair of linear equation Hence, the cost of 1 pencil be Rs 3 cost of 1 pen be RsSubtract x from both sides Subtract x from both sides y=3x − y = 3 − x Divide both sides by 1 Divide both sides by − 1 \frac {y} {1}=\frac {3x} {1} − 1 − y = − 1 3 − x Dividing by 1 undoes the multiplication by 1Xy=1 Answer by Edwin McCravy () ( Show Source ) You can put this solution on YOUR website!
3 Now speaking of x y = 3, this is what you need to graph first as a dashed line, since the presence of the inequality sign <Tells us that the two sides are not equal and therefore the points on the line x y = 3 do not satisfy the inequality and are not included in the solution setA linear equation is an equation for a straight line These are all linear equations y = 2x 1 5x = 6 3y y/2 = 3 − x Let us look more closely at one example Example y = 2x 1 is a linear equation The graph of y = 2x1 is a straight line When x

Answer Step by step solution by experts to help you in doubt clearance &Use the intercept method to graph xy=3 Step 1 Intercepts occur when one of the coordinates is equal to 0 So the yintercept occurs at x=0 and the xintercept occurs at y=0 Step 2 It takes two points to make a line So use these intercepts points Step 3 When x=0, then 0y=3 or y=3 So we have point (0,3) Step 4 When y=0, then x0=3 or
