Someone how do you do this problem

2x+4y=30

I am not sure exactly what you need, but here is what I got :))

(we have two variables so we cannot have an exact answer)

Solve for x:

(given) 2x + 4y = 30

(subtract 4y from both sides) 2x = -4y + 30

(divide both sides by 2) x = -2y + 15

Solve for y:

(given) 2x + 4y = 30

(subtract 2x from both sides) 4y = -2x + 30

(divide both sides by 4) y = -x + 7

Y = mx + b form:

(same as above)

y = -x + 7

answer

you start with $5 and save $10 a week until you have at least $45wer
