we are given
[tex] 0.5x-0.75>3.25 [/tex]
Since, we have to solve for x
so, we will isolate x on anyone side
step-1: Add both sides 0.75
[tex] 0.5x-0.75+0.75>3.25+0.75 [/tex]
[tex] 0.5x>4 [/tex]
step-2: Divide both sides by 0.5
[tex] \frac{0.5x}{0.5} >\frac{4}{0.5} [/tex]
[tex] x>8 [/tex]
so, we get
[tex] x>8 [/tex].............Answer
