In the equation \( a + 3(5a + 8) = 72 \), how do you find \( a \)?

you would look at pemdas or order of operations after () you would do multiplication so a+3(5a+8)=72 first you do 3 times (5a+8) and use the distrubtive property a+15a+24=72 so add like terms 16a+24=72 subtract 24 from both sides 16a=48 divide both sides by 16 a=3

a + 3 ( 5 a + 8 ) = 72 First you want to multiple 3(5a+8): a + ( 15 a + 24 ) = 72 Next, add a + 15a: 16 a + 24 ) = 72 Then, subtract 24 from both sides: 16 a = 48 Finally, divide both sides by 16: a = 3

To solve the equation a + 3 ( 5 a + 8 ) = 72 , distribute the 3, combine like terms, isolate the variable, and solve for a . The final answer is a = 3 .
