(m/9) - 7 = -8
To solve this, we must follow the order of operations, commonly referred to as PEMDAS
P = PARENTHESES FIRST
E = EXPONENTS SECOND
M = MULTIPLICATION THIRD/FOURTH (Depending on placement in equation)
D = DIVISION THIRD/ FOURTH (Depending on placement in equation)
A = ADDITION FIFTH/SIXTH (Depending on placement in equation)
S = SUBTRACTION (Depending on placement in equation)
When solving, you ALWAYS go left to right
So back to the equation:
(m/9) - 7 = -8
The first step would be to add 7 on both sides to isolate the (m/9) term to one side only
(m/9) = -1
Next, we multiply by 9 to cancel out and isolate the m variable for which you are solving for
m = -9
Lastly, we get our answer of: m = -9
