In math for we have:
2x-2=x+64
which turns into:
x=66
(subtract x from right) & (add two from left)
The formula of a slope:

We have the points (2, 5) and (4, 10). Substitute:

This means that 2.5mm of rain falls every hour
<span>4x+2(3x-9)=42
first we want to distribute the 2 using the distributive property
4x+6x-18=42
Then we simplify
</span><span>10x-18=42
we add 18 to both sides
10x=60
divide both side by 10
x=6</span>
Answer: sum=1 subtrahend=2
