Answer:
-12
Step-by-step explanation:
The Equation:
z + 7 = -5
Solve for the variable, z by isolating it. Note the equal sign, what you do to one side, you do to the other.
Note the rule PEMDAS.
PEMDAS is the order of operation & =
Parenthesis
Exponents (& roots)
Multiplication
Division
Addition
Subtraction
Isolate the variable. To do so, subtract 7 from both sides:
z + 7 = -5
z + 7 (-7) = -5 (-7)
z = -5 - 7
Simplify:
z = -5 - 7
z = -12
-12 is your value for z.

F(x) = 2 x - 5
15 = 2 x - 5
2 x - 5 = 15
2 x = 15 + 5
2 x = 20
x = 20 / 2
x = 10
