Hope to help you oh, do not understand can continue to ask

0.75x-5x%=17.5
How to solve it
Write the process, too

0.75x-0.05x=17.5
So 0.7x = 17.5
So x = 25

17.5+5x=75x

17.5+5x=75x
75x-5x=17.5
70x=17.5
x=17.5÷70
x=0.25

Solving equation √ 3x & # 178; = 5x

√3x²=5x
X (root 3x - 5) = 0
X = 0 or x = 5 / radical 3
