Answer:

[tex]\frac{1}{5} (2x+10)=4[/tex] [tex]x=5[/tex]

[tex]\frac{1}{3} (3x+9)=9[/tex] [tex]x=6[/tex]

Step-by-step explanation:

[tex]\frac{1}{5} (2x+10)=4[/tex]

Multiply both sides of the equation by 5.

5 · [tex]\frac{1}{5}[/tex] · [tex](2x+10)=[/tex] 5 · 4

Simplify both sides of the equation.

[tex]2x+10=20[/tex]

Subtract 10 from both sides of the equation.

[tex]2x=10[/tex]

Divide each term by 2 and simplify.

[tex]x=5[/tex]

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

[tex]\frac{1}{3} (3x+9)=9[/tex]

Substitute x for 6

[tex]\frac{1}{3} (3(6)+9)=9[/tex]

Multiply 3 · 6

[tex]\frac{1}{3} ((18)+9)=9[/tex]

Add 18 + 9

[tex]\frac{1}{3} (27)=9[/tex]

Divide [tex]\frac{1}{3}[/tex] ÷ 27

9 = 9
