Answer:

X = 10

Step-by-step explanation:

Multiply both sides of the equation by 5

x + 2x - 60 = -30

Collect like terms

3x - 60 = -30

Move constant to the right-hand side and change its sign

3x = -30 + 60

Calculate the sum

3x = 30

Divide both sides of the equation by 3

x = 10

Solution

x = 10

Answer: x = 10

Step-by-step explanation:

1/5x + 2/5x - 12 = -6    Add 12 to both sides

                   +12    +12

1/5x + 2/5x = 6     Combine like terms on the left side

3/5x = 6         Divide both sides by 3/5

x =  10
