Question

What is the solution to the linear equation?

2.8y + 6 + 0.2y = 5y – 14
A) y = –10
B) y = –1
C) y = 1
D) y = 10

Answer 1

Explanation:

D)10

Answer 2

it's definitely D) 10

2.8y + 6 + 0.2y = 5y - 14 *add 2.8y and 0.2y (like terms)
3y + 6 = 5y - 14 *subtract 3y from both sides
6 = 2y -14 *add 14 to both sides
20 = 2y *divide both sides by 2
10 = y
