Question 331920
Solve for X
1. {{{((4x+3))/((2x-1))}}} = {{{2/5}}}
on this one you cross multiply, resulting in
5(4x+3) = 2(2x-1)
:
20x + 15 = 4x - 2
20x - 4x = -2 - 15
16x = -17
x = {{{-17/16}}}
:
:
2. {{{x/5-((2x-5)/(3))=3/4}}}
Multiply each term by 60 to get rid of the denominators, resulting in
12x - 20(2x-5) = 15(3)
:
12x - 40x + 100 = 45
:
12x - 40x = 45 - 100
:
-28x = -55
x = {{{(-55)/(-28)}}} = {{{55/28}}}
