Question

Solve for x:

Plzzzzzzzzzz

Answer 1

1: x=18 2: x=7 3: x=12

Explanation:

1: 7x+3=9x-33

2x=36

x=18

2: 16x+(6x=26)=180

22x=154

x=7

3: (10x-17)-(2x-3)=90

8x-14=104

x=12

Answer 2

Answer and Step-by-step explanation:

1.

7x + 3 = 9x - 33

Subtract 7x from both sides, and add 33 to both sides of the equation.

36 = 2x

Divide both sides by 2.

x = 18

2.

6x + 26 + 16x = 180

Combine like terms.

22x + 26 = 180

Subtract 26 from both sides of the equation.

22x = 154

Divide 22 from both sides of the equation.

x = 7

3.

90 + 2x - 3 = 10x - 17

Add 17 to both sides of the equation, subtract 2x from both sides of the equation and combine like terms.

104 = 8x

Divide 8 from both sides of the equation.

x = 13
