Given that t<span>he expression
represents the total length across the front of the mansion. Let the length of side I be a, then
</span>
U is 10. If you subtract 11 first to get the variable and it's coefficient on its own, you see that 3u=30. To get the u on its own, you divide both sides by three. This gives you u=10

We have 60 gallons of 20% antifreeze.
How much 70% antifreeze do we add to get 60% antifreeze?
We'll make "x" the gallons of 70% we must add.
.20 * 60 + .70 x = .60 * (60 + x)
12 + .70x = 36 + .60x
.10x = 24
x = 240 gallons of 70% antifreeze.
