Question

Solve for the value of x. Show each of your steps. 7y=8x - 14 ; y= 6

Answer 1

7(6)=8×-14
42=8×-14
42+14=8×
56/8=8×/8
×=7

Answer 2

when y=6, then in equation 7y=8x-14 we write 6 instead of y:
7×6=8x-14
42=8x -14
8x-14=42 (now we add 14 to both sides of equation)
8x=56 (now we divide by 8 both sides of equation)
x=7

Answer: x=7
