Question

Solve 2t + 1 = 3 Question 17 options: a) 1 b) 2 c) -2 d) -1

Answer 1

a) 1

Explanation:

2t + 1 = 3

Subtract 1 on both sides

2t = 2

two divided by two equals 1

t = 1

Answer 2

Answer: t = 1

Explanation:

We're asked to solve the following equation :

`\implies\bf{2t+1=3}`

In order to solve it, I'll isolate t.

So first, I'm going to subtract 1 from both sides :

`\implies\bf{2t=2}`

T is not on its own, because we still need to divide both sides by 2 :

`\implies\bf{t=1}`

Therefore, t = 1. Choice a) is the right one.
