Sovle for x. 2x + 6 = - r - 15
Igoryamba

Answer:

x = \frac{-r - 21}{2}

Step-by-step explanation:

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

PEMDAS =

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

First, subtract 6 from both sides:

2x + 6 (-6) = -r - 15 (-6)

2x = -r + (-15 - 6)

2x = -r + (-21)

2x = - r - 21

Next, divide 2 from both sides:

\frac{2x}{2} = \frac{-r - 21}{2}

x = \frac{-r - 21}{2}
