Question

The point (x, -3) is a solution to the equation. What is the value of x?
-4y + 5x = 17

Answer 1

Solution :

Given ( x , -3 ) is a solution of the

equation -4y + 5x = 17

substitute x = x , y = -3 in the equation,

we get

-4(-3) + 5x = 17

=> 12 + 5x =17

=> 5x = 17 - 12

=> x = 5/5

=> x = 1

Therefore ,

x = 1
