Answer:
x = 45/13, also x = 3 6/13
Step-by-step explanation:
is = equal sign
of = multiply
<u>Equation:</u>
To do this, you could easily do communitive property of multiplication, but to make it more understandable I will use reversing.
1. Simplify. Multiply - Divide.

2. Factor out common term 5.

3. Multiply both sides by 3.

4. Expand.

5. Add <em>10x</em> to both sides.

Simplify. <em>3x + 10x = 13x.</em>

Divide both sides by 13.

Mixed Number =
.
You can also use distributive property. The formula for this problem is:
.
Add 5 and eliminate parentheses
... y = -2x +6 +5
Simplifying, you get
... B. y = -2x +11
