Plug -7 in for where ever you see the variable p if the final answer is equal to each other then -7 is a solution to the equation
4 × (-7) - (-7 + 9) = 5 × (-7) + 5
Use the rules of PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)
Parentheses
4 × (-7) - (-7 + 9) = 5 × (-7) + 5
4 × (-7) - 2 = 5 × (-7) + 5
There are no exponents so go to the next step
Multiplication (apply this from left to right)
4 × (-7) - 2 = 5 × (-7) + 5
-28 - 2 = 5 × (-7) + 5
-28 - 2 = 5 × (-7) + 5
-28 - 2 = -35 + 5
There is no division so go to the next step
Addition
-28 - 2 = -35 + 5
-28 - 2 = -30
Subtraction
-28 - 2 = -30
-30 = -30
-30 = -30
-7 is a solution to this equation because when evaluated both sides equals -30
Hope this helped!
