Answer:
12x + 4z
Step-by-step explanation:
Given: 2/3 (18x + 6z)
Multiply the fraction 2/3 into each term
(
)*18x + (
)*6z
x +
z
12x + 4z
2a+10b-c + -3a +5b + c = -a +15b
If we take both sides of the equation
and <em>multiply either expression by 3</em>, the equality becomes

Multiplication of both sides of an equality by the same number keeps the equality true, and we call this property the multiplication property of equality.
Y=mx+b
m= slope so slope= .5
b= y intercept so y intercept=0
