Question

In the equation 36 = 12 + (15t) - 6, t equals:

a) 3
b) -2.2
c) 1.7
d) -2.8
e) 2

Answer 1

Explanation

Our task is to find the value of t.

36 = 12 + 15t - 6

Combine like terms:

`\sf{36 = 12 - 6 + 15t}`

`\sf{36 = 6 + 15t}`

Subtract 6 from both sides:

`\sf{36 - 6 = 15t}`

`\sf{30 = 15t}`

Divide both sides by 15.

`\sf{2 = t}`

Therefore, t = 2.
