Simplify equations HELP NOW!!

Mathematics
1 answer:
Anna [14]3 years ago
6 0

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
