Question

4a – 16 = a - 15 how do I solve ​

Answer 1

a =
`(1)/(3)`

Explanation:

4a -16 = a - 15

both left and right -a

then

4a - 16 -a = a - 15 -a

then

4a -a -16 = a -a -15

then

3a -16 = -15

both left and right + 16

then

3a -16 + 16 = -15 + 16

then

3a = 1

both left and right ÷3

then

3a ÷ 3 =1 ÷ 3

then

a =
`(1)/(3)`
