Question

What is x?
-2 + 3x = 5x - 8

Answer 1

X = 3

Explanation:

-2 + 3x = 5x - 8

+8 Because -8 is lower then -2 we start by doing the opposite and +8 to -2

6 + 3x = 5x

-3x Because now we have to do the opposite on the variable too.

6 = 2x

/2 Because you have to divide the integer by the variable

x = 3

Answer 2

x = 3

Explanation:

-2 + 3x = 5x - 8

add 8 to both sides:

-2 + 3x + 8 = 5x - 8 + 8

6 + 3x = 5x

subtract 3x from both sides:

6 + 3x - 3x = 5x - 3x

6 = 2x

divide both sides by 2:

6/2 = 2x/2

x = 3

check: when x = 3

-2 + 3(3) = 5(3) - 8

-2 + 9 = 15 - 8

7 = 7
