Answer

a=4

Work Step by Step

Start with the given equation: 5a-15+9a=3a+29 Put all like terms on the same side of the equation by adding 15 and subtracting 3a from both sides of the equation. The resulting equation is 5a+9a-3a=29+15 Combine all like terms to get 11a=44 Lastly, divide by 11 on both sides of the equation to get a=4.
