Question

Find the value of x.

14.) 79 = 3x - 5
15.) 7x + 2 = 3x + 8

A) x = 28, x = 3
B) x = 24, x = 5
C) x = 16, x = 6
D) x = 22, x = 4

Answer 1

To find the value of x in the equations, we need to isolate x. The first equation simplifies to x = 28, while the second equation simplifies to x = 1.5.

Step-by-step explanation:

To find the value of x in the equation 79 = 3x - 5, we need to isolate x. First, we can add 5 to both sides of the equation to get 3x = 84. Then, we divide both sides by 3 to find that x = 28.

To find the value of x in the equation 7x + 2 = 3x + 8, we want to isolate x again. To do this, we subtract 3x from both sides to get 4x + 2 = 8. Next, we subtract 2 from both sides to get 4x = 6. Finally, we divide both sides by 4 to find that x = 3/2 or 1.5.
