Answer:

x = -3

Step-by-step explanation:

3x + 2 = x + 4(x + 2)

Get rid of the parentheses by using distribution

4 * x = 4x

4 * 2 = 8

3x + 2 = x + 4x + 8

Combine like terms

x + 4x = 5x

3x + 2 = 5x + 8

Isolate the x

3x + 2 = 5x + 8

-2 -2

3x = 5x + 6

-5x -5x

-2x = 6

Now, simplify it

-2x = 6

---- -----

-2 -2

x = -3

Kisachek [45]

Step-by-step explanation:

2x +8y = 54

x + 9y = 67

x = 67 - 9y

2(67-9y) + 8y = 54

434 - 18y + 8y = 54

434 - 10y = 54

10y = 54 - 434

10y = -380

y = -38
