Answer:

Solution of the inequality is #x<2#

Explanation:

Given:

The inequality # -5x+7 > -3#

Subtract #7# from both sides of the inequality

# rArr -5x+7-7 > -3-7#

# rArr -5x+cancel 7-cancel 7 > -3-7#

#rArr -5x > - 10#

Multiply both the sides by #(-1)#

Please remember to reverse the inequality

#rArr (-5x)(-1) < (- 10)(-1)#

#rArr 5x < 10#

Divide both sides by 5

#rArr (5x)/5 < 10/5#

#rArr (cancel 5x)/cancel 5 < cancel 10 ^ color(red)(2) /cancel 5#

#rArr x < 2#

Hence #x<2# is the required solution.
