Question

Does anyone know the answers to these two questions?

Answer 1

so you're stuck on how to solve 123 = x + 75 right?

Answer 2

Yeah

Answer 3

to isolate x, we need to do something to both sides that moves that 75 over

Answer 4

Okay

Answer 5

we are adding 75 to x

so we can subtract 75 from both sides to undo this operation

Answer 6

Okay

Answer 7

on the right side, the +75 and the -75 will combine to 0 and go away

Answer 8

what do you get when you subtract 75 from both sides

Answer 9

48?

Answer 10

correct, so x = 48

Answer 11

you'll use this same idea to solve the other 2 equations

Answer 12

Oh okay, that's easy. Thank you so much!

Answer 13

you're welcome
