Question

Look for y in the following equation and justify each response

5x+y=18

Answer 1

y=18-5x

Explanation:

Objective: Find y

5x+y=18

to find y we must get y by its self, to get y by its self we must subtract both 5x from both sides of the equation

5x+y=18

-5x -5x

now we simplify:

y=18-5x

Hence, the final answer is y=18-5x

Answer 2

it depends on the value of x

Explanation:

if x was 2 for example, y would be 8 since 5*2 is 10 + 8 = 18

if x was 3, y would be 3 since 5*3 is 15 + 3 = 18
