1. 2(1-3x)+7 = -4x+27
2. 2-6x+7 = -4x+27
3. 9-6x = -4x+27
4. 9-2x = 27
5. -2x = 18
6. x = -9
1. Distribute the two into the parentheses. This is done by multiplying each number by two.
2. Combine Like Terms (In this case the two and the seven on the left side)
3. Isolate the Variable. Start this by getting rid of the -4 on the right. To do this, simply add 4x to both sides.
4. Get rid of the nine on the left by subtracting nine from both sides.
5. Divide both sides by -2
6. Your solution
