Rewrite one of the two equations above in the form ax+by=c, where a, b,c are constants, so that the sum of the new equations and the unchanged equations from the original system results in an equation in one variable

I would rewrite the second equation like this: multiply both sides by 4 to get

and then the sum of this rewritten one and the top row equation will be

which is an easy to solve equation with one variable (y)

1 is c

2 is a

3 is a

step-by-step explanation:

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !
