Question

What is t? 2(t-1)=4
______________________

Answer 1

t = 3

Explanation:

`2(t-1)=4`

`2t-2=4`

`2t=4+2`

`2t=6`

`t=6/2`

`t=3`

Hope this helps.

Answer 2

t = 3

Given equation: 2(t-1) = 4

Distribute inside the parenthesis:

2(t) + 2(-1) = 4

simplify the following:

2t - 2 = 4

shift the 2 towards right side:

2t = 4 + 2

simplify the following:

2t = 6

divide both sides by 2:

2t/2 = 6/2

simplify the following:

t = 3

Now to confirm the answer, simply substitute t = 3 in the equation

2(t - 1) = 4

2(3 - 1) = 4

2(2) = 4

4 = 4

Hence, confirmed.
