Question

Rezolvati:

3 - $\frac{1-x}{2}$ = (1/2)² + 0,75

Answer 1

3-(1-x)/2=(1/2)²+0,75
3-(1-x)/2=1/4+75/100
3-(1-x)/2=1/4+3/4
3-(1-x)/2=(1+3)/4
3-(1-x)/2=4/4
(1-x)/2=3-1
(1-x)/2=2
1-x=4
x=1-4=-3

Answer 2

3 - (1 - x)/2 = 1/4 + 75/100
3 - (1 - x)/2 = 1/4 + 3/4
12 - 2(1 - x) = 1 + 3
- 2 + 2x = - 12 + 4
2x = - 8 + 2
x = - 6/2
x = - 3
