Question

Solve for y. Round your answer to the nearest tenth and explain all steps. -3=15+4y

Answer 1

Answer: y = -4.5

Step-by-step explanation:

Given expression

-3 = 15 + 4y

Subtract 15 on both sides

-3 - 15 = 15 + 4y - 15

-18 = 4y

Divide 4 on both sides

-18 / 4 = y / 4

$\boxed{y=-4.5}$

Answer 2

Answer:

y = -4.5

Step-by-step explanation:

-3 = 15 + 4y or…

4y + 15 = -3

Step 1. Look at the number that is being added to the product of a number and 4 and if it is a positive number, subtract that number by itself to -3 and if it is a negative number, add that number by itself to -3.

4y = -3 - 15

4y = -18

Step 2. Solve for y

y = -18/4

y = -4.5

The answer is already in nearest tenth
