Y=4x+7 ; y=10 what does x=

Answer 1

Steps to solve:

y = 4x + 7; y = 10

~Substitute

10 = 4x + 7

~Subtract 7 to both sides

10 - 7 = 4x + 7 - 7

~Simplify

3 = 4x

~Divide 4 to both sides

3/4 = 4x/4

~Simplify

3/4 = x

Best of Luck!

Answer 2

x = 3/4

Explanation:

Y=4x+7

Let y =10

10 = 4x+7

Subtract 7 from each side

10-7=4x+7-7

3 = 4x

Divide each side by 4

3/4 = 4x/4

3/4 =x
