Question

If 4a - 3 = 9, what is the value of 4a + 1?! A: 13 B: 3 C:49 D: 5

Answer 1

Answer:

A: 13

Step-by-step explanation:

4a-3 = 9

add 3 to both sides

4a-3 = 9

  +3   +3

the -3 and +3 will cancel each other out

and from adding the 3 to the 9 will turn the 9 into 12!

Now your equation will look like this

4a = 12

Next divide both sides by 4. the 4 will cancel out the other 4.\

now you will have your answer

a = 3

so now substitute the A with 3 in

4a+1

so it will be

4(3)+1

4 times 3 is equal to 12

then 12+1 = 13

I hope this helps! :)
