Question

Twice y decreased by 10 equals 18.

Answer 1

Answer:

y = 14

Step-by-step explanation:

Step 1: Write equation

2y - 10 = 18

Step 2: Solve for y

1. Add 10 to both sides: 2y = 28
2. Divide both sides by 2: y = 14

Step 3: Check

Plug in y to verify it's a solution.

2(14) - 10 = 18

28 - 10 = 18

18 = 18

Answer 2

Answer:

y=14

Step-by-step explanation:

Problem set up looks like this: 2y-10=18

2y=28

y=14
