Question : 8

Total: 40

Solve:

(x-1)=\,\frac{1}{2}(x+2)

Solution:

Concept:

Eliminate the fraction by multiplying both sides of the equation by the denominator.

Explanation:

Given:

(x-1)=\frac{1}{2}(x+2)

Multiply both sides by

2

to remove the fraction:

2 \times (x-1) = 2 \times \frac{1}{2}(x+2)

2(x-1)=x+2

Expand the bracket on the left:

2x-2=x+2

Bring the variable terms together and constant terms together:

2x-x=2+2

x=4

Answer:
