Question

-PLEASE HURRY- this is the third time I’ve asked this question and no one has given me an answer.

How do I evaluate/solve multi-step expressions?

Answer 1

Explanation:

Solve 3y + 10.5 = 6.5 + 2.5y.

Add -2.5y to both sides so that the variable remains on one side only. Now isolate the variable by subtracting 10.5 from both sides. Multiply both sides by 10 so that 0.5y becomes 5y, then divide by 5. Check your solution by substituting -8 in for y in the original equation.
