Can someone help me real quick I'm lowkey confused you purchased paint for the rooms in your home. you have 1.5 cans of paint left. you painted 4 rooms and each room required 2cans of paint.

you spilled 1/2 of a can of paint. how many cans of paint did you purchase?

a - solve the problem by working backward.

b - solve the equation x - 2 / 4 = 2 how does the amwer compare to part (a)?

10

Step-by-step explanation:

So first it wants you to solve working backwards. This basically means to add up what you used and spilled, opposite of subtracting or using it. I will show that below.

a - You have 1.5 cans left. You painted 4 rooms, each needing 2 cans, making it 8 cans. Now you bought 9.5 cans. Then .5 of a can got spilled. So you bought 10 cans of paint.

Next is solving the equation. I'll explain below.

b - So simplify the equation, which will get x = 2.5. x represents the amount of paint used to paint each room. To represent the 4 rooms, multiply both sides by 4.

4x = 10. So, both b and a have the same answer, 10.
