Question

Solve 2x + 5y = 10 for y.

y = 2x + 2

y = –2x + 10

y = -2/5x + 2

y = 2/5x + 10

Answer 1

5y= -2x+10
y= -2/5 x+10
So it would be D

Answer 2

Firstly move the 2x to the other side - via subtraction - so the y part is isolated:
5y = 10 - 2x

Then move the 5 over to the other side - via division - so the y stands alone:
y = (10 - 2x) / 5

Finally divide through - simplify:
y = 2 - 2/5x

Which when rearranged is answer 3:
y = -2/5 x + 2

C
