Question

What is the value of t in the equation?
-3t – 4 (t – 5) = 48

Answer 1

Explanation:

-3t-4t+20=48

-7t=28

t=-4

Answer 2

t = -4

Explanation:

-3t – 4 (t – 5) = 48

Distribute

-3t -4t +20 = 48

Combine like terms

-7t +20 = 48

Subtract 20 from each side

-7t +20-20 = 48-20

-7t = 28

Divide by -7

-7t/-7 = 28/-7

t = -4
