Question

Solve for X ㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤ

Answer 1

Answer:

(x - 8) + (2x - 4) = 15

3x - 12 = 15

+12       +12

3x = 27

Divide by 3 on both sides:

x = 9

Answer 2

Answer:

x = 9

Step-by-step explanation:

➼first, let's put it into an equation

(x - 8) + (2x - 4) = 15

➼next, add up the common terms

-since there are two variables with x and two number variables, we will rewrite the equation and solve

(-8 - 4) + (2x + x) = 15

-8 - 4 = -12

2x + x = 3x

plug in:

-12 + 3x = 15

➼now get x alone by first getting rid of 12

-do this by doing opposite and adding 12 to everything

-12 + 12 = 0

12 + 15 = 27

plug in:

3x = 27

divide 3 both sides

27/3 = 9

3/3 = 0

➼x = 9
