A+a+3=a+13
2a+3=a+13
From here you want the variables on the same side, so you would subtract the a from a+13 and move it to 2a+3
2a+3=a+13
-a -a
a+3=13
Now you want the numbers on the same side
a+3=13
-3 -3
a=10
Answer:
multiply both sides by 3x + 7
Step-by-step explanation:
this will eliminate the fraction in the equation and therefore make it easier to isolate x

Answer:

Step-by-step explanation:
Use the distributive property.
<u>Distributive property:</u>
<h3>
⇒ A(B+C)=AB+AC</h3>
⇒ 5*5=25
⇒ 5*8=40
<u>Rewrite the problem.</u>
⇒ 5*5a+5*8
<u>Solve.</u>
<u>Multiply.</u>
⇒ 5*5a=25a
⇒ 5*8=40
<u>Rewrite the expression.</u>
<u>⇒ = 25a+40</u>
- <u>Therefore, the correct answer is 5(5a+8).</u>
