46

Step-by-step 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 is the order of operation, and stands for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

First, subtract 8 from both sides of the equation:

2x + 8 (-8) = 16 (-8)

2x = 16 - 8

2x = 8

Next, divide 2 from both sides of the equation:

(2x)/2 = (8)/2

x = 8/2 = 4

Next, plug in 4 for x in the given expression:

x + 42

(4) + 42 = 46

46 is your answer.
