can someone help with this algebra?

Question

87 =16+f, and q+83=137, and, 107=35+x. thanks.

Answer 1

87=16+f (Subtract 16 from each side)
87-16=f

q+83=137 (Subtract 83 from each side)
q=137-83

107=35+x (Subtract 35 from each side)
107-35=x

Answer 2

87 = 16 + f
f = 87 - 16
f = 71

q + 83 = 137
q = 137 - 83
q = 54

107 = 35 + x
x = 107 - 35
x = 72

Answer 3

87 = 16 + f
f = 87 - 16
f = 71

q + 83 = 137
q = 137 - 83
q = 54

107 = 35 + x
x = 107 - 35
x = 72

Answer 4

isolate the variable...
87 = 16 + f (sub 16 from each side) f = 87 - 16

q + 83 = 137 .... q = 137 - 83

35 + x = 107 ..... x = 107 - 35



hope this helps

Answer 5

f=87-16 = 67

q = 220

x = 107-35 = 72

Answer 6

The basics of algebra equations is to get different terms on opposite sides of the equal sign. In these equations you need the numbers on one side and the variable on the other. Here's the first one:

87 -16=16 -16 +f (To keep an eq. equal do the same to BOTH sides!) This leaves>>>
71=f In this one you need to subtract 16 from both sides to leave the right side with the variable, f, by itself.

Answer 7

f=87-16
f=71

q=137-83
q=54

x=107-35
x=72

Answer 8

I assume you're trying to simplify, and get the variable on one side.

Therefore, in the first problem, you're going to try to get the f on one side, so subtract sixteen, and then subtract sixteen from the 87, and that answer equals f.

You're going to do the same thing for the rest of them.

Answer 9

87=16+f
87-16=f
71=f

q+83=137
q=137-83
q=64

107=35+x
107-35=x
72=x

Answer 10

f=71
q=54
x=72
you have to subtract from both sides in order to get the letter alone.
