Answer:

X = 1

Explanation:

-2x + 7 = 3 - ( -2x)

-2x + 7 = 3 +2x (- - = +) (+ + = +) and (different signs always negative: - + = -)

(any term or numbers moved from one side of the = sign goes from negative to positive or from positive to negative, from multiplying to dividing and from dividing to multiplying. First isolate the additions or subtractions.)

-2x + 7 = 3 + 2x

-2x + 7 - 3 = 2x

-2x + 4 = 2x

4 = 2x + 2x

4 = 4x (a number next to a letter is multiplying. It goes to the other side of the equation dividing)

4 /4 = x

X = 1
