Question

4x=3y-7 when x= 5,10,15

Answer 1

you have to re-arrange the equation to get y=...x.

Answer 2

do you know how to re-arrange equations?

Answer 3

not really

Answer 4

you can move a constant or variable on the other side,
if you change its sign. in above example, moved 7

Answer 5

before:
4x = 3y -7

after:
4x +7= 3y

7 is on the other side of the equation right?
it's now with 4x instead of 3y.

we had to change sign from - to +
