x=10

Explanation:

#5x-7=4x+3#
to make the variable positive, we shifted the smaller variable value to another side. the negative value of constant does not matter.
#5x-4x=3+7#
#x=10#
to verify whether the value of #x=10# is correct or not, we put the value of #x# into its position in the equation. remember that numbers are not shifted in the verification step.
#5(10)-7=4(10)+3#
#50-7=40+3#
#43=43#
