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

Solve: 7x = 3x + 24

• 10

• 4

• 6

• 14

Solve the equation: 4x - 5x + 9 = 5x - 9

• x=3

• x=-3

• x=-9

• x=9

Solve: 10x + 9 = 4x - 9

• x=3

• x=0

• x=-3

• x=18

Solve: 2(4x-3) - 8 = 4 + 2x

• x=5/3

• x=3

• x=1

• x=2

The objective when solving an equation is to....

• isolate the variable.

• check the solution.

• guess and check.

• Combine Like Terms.
