someone help nd explain

3. anonymous

what do you mean by y equals quantity x plus 7 divided by 5

so the equation is $y = \frac{x +5}{7}$ so to find the inverse, swap x and y... so it becomes $x = \frac{y + 5}{7}$ now make y the subject of the equation

i dont get it :/

6. campbell_st

the final result will be the inverse of the original equation

7. campbell_st

ok... good luck then

8. campbell_st

but your goal is to get y on its own... so start by multiplying both sides of the equation by 7

9. anonymous

so its B

10. campbell_st

if that's what you think, then select it.
