Answer:

Both expressions equal 5 when substituting 2 for x because the expressions are equivalent.

Step-by-step explanation:

x=2

1/2(x) + 4

1/2(2) +4

1+4 = 5

x + 6 -1/2(x) -2

2+6 -1/2(2) -2

8 - 1 -2 = 5

Answer: $\bold{n=\dfrac{11}{6}}$

Step-by-step explanation:

$\dfrac{3n-2}{5}=\dfrac{7}{10}\\\\\\10(3n-2)=5(7)\qquad \longrightarrow \quad \text{(cross multiplied)}\\\\30n-20=35\qquad \longrightarrow \quad \text{(distributed)}\\\\30n=55\qquad \longrightarrow \quad \text{(added 20 to both sides)}\\\\n=\dfrac{55}{30}\qquad \longrightarrow \quad \text{(divided 30 from both sides)}\\\\n=\dfrac{11}{6}\quad \longrightarrow \quad \text{(simplified fraction)}\\\\\\\large\boxed{n=\dfrac{11}{6}}\\$
