Simplify equations HELP NOW!!

Anna [14]

Answer:

$\frac{1}{5} (2x+10)=4$ $x=5$

$\frac{1}{3} (3x+9)=9$ $x=6$

Step-by-step explanation:

$\frac{1}{5} (2x+10)=4$

Multiply both sides of the equation by 5.

5 · $\frac{1}{5}$ · $(2x+10)=$ 5 · 4

Simplify both sides of the equation.

$2x+10=20$

Subtract 10 from both sides of the equation.

$2x=10$

Divide each term by 2 and simplify.

$x=5$

--------------------------------------------------------------------

$\frac{1}{3} (3x+9)=9$

Substitute x for 6

$\frac{1}{3} (3(6)+9)=9$

Multiply 3 · 6

$\frac{1}{3} ((18)+9)=9$

Add 18 + 9

$\frac{1}{3} (27)=9$

Divide $\frac{1}{3}$ ÷ 27

9 = 9
