Question

2(x+$\frac{1}{2}$)+5=$\frac{1}{2}$ pentru azi caci daca nu iau 2

Answer 1

$\displaystyle 2\left(x+ \frac{1}{2} \right)+5= \frac{1}{2} \\ \\ 2x+ \frac{2}{2} +5= \frac{1}{2} \\ \\ 2x+1+5= \frac{1}{2} \\ \\ 2x \cdot 2+1 \cdot 2+5 \cdot 2=1 \\ 4x+2+10=1 \\ 4x=1-2-10 \\ 4x=-11 \\ \\ \boxed{x=- \frac{11}{4} }$

Answer 2

2(x+1/2)+5=1/2=2x+6=1/2
2*2x+2*6= 2 1/2
4x+12=1
4x+12-12=1-12
4x=-11
4x/4= -11/4
x= - 11/4
