4(3x + 7) = 7

1) You can't do anything until you get rid of the parentheses. Use distributive property to get rid of those.

**12x + 28 = 7**

2) Now do the order of operations backwards. The first thing (going backwards) is addition/subtraction. What do you have in *your problem*? You have addition. The opposite of addition is subtraction.

**12x + 28 = 7**

** -28 -28**

**12x = -21**

3. Now you have 12x = -21. What operation is being used in the equation? Multiplication is. The opposite of multiplication is division. Now divide both sides by 12.

**12x = -21**

**x = -1.75**

4(3x+7)=7

(3x+7)=7/4 divide both sides by 4

3x = 7/4 - 7 subtract 7 from both sides

x = (7/4 - 7)/3 divide both sides by 3

x = 7/12 -7/3 expand the parenthesis

x = 7/12 - 28/12 find common denominator (* by 4/4)

x = -21/12 subtract

**x = -7/4** simplify
