Question

What value of x makes this equation true?
3x + 6 = -2x + 4

Answer 1

Exact Form:

x=−2/5

Decimal Form:

x=−0.4

Explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Answer 2

x = -2/5

Explanation:

to solve, we need to put x on one side of the equation

3x + 6 = -2x + 4 < subtract 4 from both sides

3x + 2 = -2x < subtract 3x from both sides to get x on one side of the equation

2 = -5x < divide both sides by -5 to get x alone

2/-5 = -2/5

-5x/-5 = x

-2/5 = x

the value of x that makes this equation true would be -2/5
