Question

check whether x=2 and y=-1 is a solution of pair of linear equation 2x-3y=7 and5x+3y=7​

Answer 1

Step-by-step explanation:

we have,

$2x - 3y = 7 \\ 5x + 3y = 7$

now to check whether the given pair of coordinates is a solution for the pair of linear equations, we simply plug them into the equation.

The first equation,

$2(2) - 3( - 1) = 7 \\ 4 - ( - 3) = 7 \\ 4 + 3 = 7 \\ 7 = 7$

which is true

Now for the second equation,

$5(2) + 3( - 1) = 7 \\ 10 + ( - 3) = 7 \\ 10 - 3 = 7 \\ 7 = 7$

which is also true

Hence, we can conclude that

$x = 2 \\ y = - 1$

is a solution for the given equations
