Answer:

Step-by-step explanation:

Equation

2(x + 4) = x - 1

Solution

2x + 8 = x - 1                Subtract x from both sides

2x-x + 8 = - 1                Combine the left

x + 8 = - 1                     Subtract 8 from both sides

x + 8-8 = - 1-8

x = - 9

Check

<em>LHS</em>

2(-9 + 4)

2(- 5)

-10

<em>RHS</em>

-9 - 1

- 10

When g(x) = -30, x = -10
To solve, make -30 equal to 2(x-5):
-30 = 2(x-5)
-30 = 2x -10
-20 = 2x
-10 = x
