Need help with this algebra equation 16x-15-9x=13

Report as

16x - 15 - 9x =13
16x - 9x = 13 + 15
(16 - 9)x = 28
7x = 28
x = 28/7 = 4
You got it !?

19x-15=13

Add 15 to 13 then you subtract 9x from 16x and you will have 7x= 28 then you proceed to take 28 and devide by 7 therefore, x=4 ^-^

variables on one side, like number on the other so add 15 to both sides which equals 16x-9x=28 then solve 16x-9x which is 7x so 7x=28 now divide each side to get x alone and the answer is x=4
