Answer:
Step-by-step explanation:
1) -3 + [tex]\frac{1}{2} n[/tex] = [tex]\frac{1}{2}[/tex](-n + 14)
-3 + [tex]\frac{1}{2} n[/tex] = [tex]\frac{-1}{2} n\\[/tex] + 7
[tex]\frac{1}{2} n[/tex] + [tex]\frac{1}{2} n[/tex] = 3+ 7
[tex]\frac{1}{4\\} n[/tex] = 10 bhhhhhhhhhhhhhhhhhh
n = 10 : 1/4
n = 40
2) -3 + [tex]\frac{1}{2} n[/tex] = [tex]\frac{1}{2}[/tex](-n + 14)
-3 + [tex]\frac{1}{2} n[/tex] - [tex]\frac{1}{2}[/tex](-n + 14) =0
-3 + [tex]\frac{1}{2} n[/tex] + [tex]\frac{1}{2}[/tex]n - 7 = 0
[tex]\frac{1}{4} n\\[/tex] - 10 = 0
[tex]\frac{1}{4}[/tex]( n - 40 ) = 0
n- 40 = 0
n = 40
