Question

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

Answer 1

Answer: x= 1

Explanation:

-4y+5x=17

-4.(-3) + 5x=17

12 + 5x = 17

5x= 17-12

x= 5

5

x= 1

Answer 2

x = 1

Explanation:

-4v+5x=17 give that (x,-3) is the solution

so x coordinate is = x (unknown)

y coordinate is = -3

substitute the value of y in -4y+5x=17

therefore

-4(-3)+5x=17

12+5x=17

5x=17-12

5x=5

x=5/5

x=1
