The value of x is 4

to show your work:
8x + 7 = 6x + 15
- 7 - 7
8x = 6x + 8
-6x -6x
2x=8
divid by 2 and it’s x = 4 :)

Solve for all values of y in simplest form.<br> 10 = |y/9|

kiruha [24]

Answer: y = -90, 90

Step-by-step explanation:

To solve this, we will isolate the variable.

Given:

10 = | $\frac{y}{9}$ |

Absolute value:

10 = $\frac{y}{9}$ & -10 = $\frac{y}{9}$

Multiply both sides of both equations by 9:

90 = y & -90 = y

Answer:

y = -90, 90
