Question

Solve the following equation.

2x + 1 = 5

1. 2
2. 5
3. 8

Answer 1

2

Step-by-step explanation:

2x + 1 = 5

The solution to the above equation can be obtained as follow:

2x + 1 = 5

Subtract 1 from both side

2x + 1 – 1 = 5 – 1

2x = 4

Divide both side by the coefficient of x i.e 2

2x/2 = 4/2

x = 2

Therefore, the solution to the equation is 2.
