#x=150#

Explanation:

#7.32=0.05x-0.18#

Add #0.18# to both sides of the equation:

#7.5=0.05x#

Divide both sides of the equation by #0.05#

#x=7.5/0.05=150#

Explanation:

#color(brown)("Lets get rid of the decimals!")#

LHS -> Left hand side
RHS -> Right hand side

So LHS = RHS# -> #100(LHS)=100(RHS)

Multiply both sides by 100

#732=5x-18#

Add 18 to both sides:

#750=5x#

Divide both sides by 5

#150=x#

Write as #x=150#
