Step-by-step explanation:

well, it is supposed to be -3.

but you are right. something is wrong or missing here.

5x + 3 = 4x

x + 3 = 0

x = -3

maybe a "+ 1" is missing on the right side ?

5x + 3 = 4x + 1

gives us

x = -2

Basically the equation is 5•2+3 which is 13 because you multiply 5 and 2 first then whatever answer you get plus 3
