What is the first step you should take to solve this problem?

1 + 4n - 6n = 1 - 8n

• subtract 8n to both sides

• multiply 6n to both sides

• combine the like terms 4n + -6n

7x = 3x + 24

• 6

• 10

• 14

• 4

What is the final answer to

10 + 2n = 8n - 2n + 10 ?

• 12

• 5

• 0

• -15

What is the goal of solving an equation with variables on both sides of the equal sign?

• Find a value of x that makes both sides of the equal sign equal to each other.

• To combine like terms on each side of the equal sign.

• Find a value of x that makes one side of the equation correct.

• To distribute/ combine terms terms on each side of the equal sign

Solve for x:
5x - 14 = 8x + 4

• x = 6

• x = -6

• x = -18/13

• x = 10/3
