Question

7. Solve the equation. x + 3 = 3x - 7 A-10 B - 12 05 OD-2

Answer 1

Answer:

C. x = 5

Step-by-step explanation:

x + 3 = 3x - 7

Add -3x and -3 on both sides.

x - 3x = -7 -3

Add or subtract like terms.

-2x = -10

Multiply -1 on both sides.

2x = 10

Divide 2 into both sides.

2x/2 = 10/2

x = 5

Answer 2

The correct answer is C : 5

Step by step:

1. Subtract -3 on both sides and get x = 3x -10

2. Subtract 3x on both sides and get -2x= -10

3. Divide -2 on both sides and get x=5 as your answer!!
