I believe it is -8y + 5x - 3
Here is the equation to find that answer A=bh+2ls+ib i got it off line if its not right im sory
Its $800 because to find interest u can use the formula I=PRT p is principal which is 500 times r which is rate-15/100(=15%) times 4
so the interest is 500×15/100×4=300
then u add 300 to 500 because the interest adds more money to the loan
The answer should be 1.8 or 1 4/5
4(m-2)=24
4m-8=24 distributive property
add 8 to each side
4m=32
divide each side by 4
m=8
