Question

I need some help please help meeee!

Answer 1

Answer:

1. A

2. C

3. B

4. B

Step-by-step explanation:

1. Subtract 4.2 on both sides of the equation so you're left with y = -0.8

2. Add 1.9 on both sides of the equation so you are left with m = 4.

3. Distribute 1/5 into (3+2z) to get 3/5 + 2/5z - 4z = -3. Combine like terms so you have 3/5 - 3 3/5z = -3. Subtract 3/5 on both sides to get -3 3/5z = -3 3/5. Divide by -3 3/5 on both sides to get z = -1.

4. Distribute 4 into (2+ t) to get 1/2t -8 -4t = 20. Combine like terms to get -3 1/2t - 8 = 20. Add 8 on both sides to get -3 1/2t = 28. Divide -3 1/2 on both sides to get t = -8.
