4x - 7 > 17
Add '7' to both sides
Hence
4x > 24
Divide both sides by '4'
Hence
x > 6
Verification ; When x = 7
4(7) - 7 = 28 - 7 = 21 which greater than 17. So its true.
NB Treat inequalities like an 'equals' sign , except when calculating with negative numbers or fractions, whereupon turn the sign around.
