Question

Solve the equation: 5x + 5 = 0

Answer 1

x = -1

Explanation:

Isolate the variable (x). Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS = Parenthesis, Exponents (& roots), Multiplication, Division, Addition, Subtraction.

First, subtract 5 from both sides

5x + 5 = 0

5x + 5 (-5) = 0 (-5)

5x = 0 - 5

5x = -5

Next, divide 5 from both sides

(5x)/5 = (-5)/5

x = -5/5

x = -1

-1 is your answer for x.

Answer 2

x = -1

Explanation:

5x + 5 = 0

Subtract 5 from each side

5x+5-5 = 0-5

5x = -5

Divide by 5 on each side

5x/5 = -5/5

x = -1
