Question

- x+4=-3x + 8
multi-step equations

Answer 1

Explanation:

this is answer

`- x + 3x = - 4 + 8 \\ 2x = 4 \\ x = (4)/(2) \\ x = 2x = 2x = 2`

Answer 2

x = 2

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 =

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

& is the order of operation.

First, add 3x and subtract 4 from both sides:

-x (+3x) + 4 (-4) = -3x (+3x) + 8 (-4)

-x + 3x = 8 - 4

Simplify. Combine like terms:

3x - x = 8 - 4

2x = 4

Isolate the variable, x. Divide 2 from both sides:

(2x)/2 = (4)/2

x = 4/2

x = 2

x = 2 is your answer.
