Question

What is the solution to 5a - 15 + 9a = 3a + 29?

Answer 1

Hi there! Thanks for asking a question here on Brainly. 

Step 1: We need to simplify both sides of the equation.

⚫ 5a−15+9a=3a+29
⚫ 5a+−15+9a=3a+29
⚫ (5a+9a)+(−15)=3a+29
     
Combine like terms

⚫ 14a +15 = 3a + 29
⚫ 14a − 15 = 3a + 29

Step 2: Subtract 3a from both sides.

⚫14a − 15 − 3a = 3a + 29 − 3a
⚫11a − 15 = 29

Step 3: Add 15 to both sides.

⚫ 11a − 15 + 15 = 29 + 15
⚫ 11a = 44

Step 4: Divide both sides by 11.

⚫ 11a11= 4411

a = 4

Answer 2

1:Simplify 5a-15+9a to 14a−15
14a-15=3a+29

2:Add 15 to both sides
14a=3a+29+15

3:Simplify 3a+29+15 to 3a+44
14a=3a+44

4:Subtract 3a from both sides
14a−3a=44

5:Simplify 14a−3a to 11a
11a=44

6:Divide both sides by 11
a=44/11

7:Simplify 44/11 to 4
a=4
