Remember
you can do anyting to an equaiton as long as you do it to both sidess
distributive property
a(b+c)=ab+ac
commutativ property
a+b=b+a
distribute
3(4x-2)=12x-6
12x-6=9+2x+5
add 6 both sides
12x+6-6=9+6+5+2x
12x+0=20+2x
minus 2x
10x=20
divide 10
x=2

How to= the number you are dividing by has a decimal move the decimal point all the way to the right counting the number of places you’ve moved it to. Then move the decimal point in the number you’re dividing the same number of places to the right
Okay so.
We have two basic equations
Tower A+ B+720 A is 720ft taller than B.
Tower A+B= 1982 Combined height is 1982ft
Replace A with B+720 in 2nd equation and solve for B
B+720+B=1982 Combine like terms
2B+720=1982 Subtract 720 from both sides
2B=1262 Divide both sides by 2
B=1262/2
B= 631ft
We know that A=B+720 so you simply need to do that addition to have the height of both towers.
