Solve each equation: Thank you
5x over 3 minus x2 over 4 = 5/12

5x over 3 minus x2 over 4 = 5/12
Is this what you meant?
(5x/3)(x2/4)=5/12
Multiply everything by 12.
12(5x/3)12(x2/4)=12(5/12)
remove parentheses
204x3x+6=5
combine terms
267x=5
7x=526
7x=21
multiply by 1
7x=21
divide both sides by 7
7x/7 = 21/7
x=3
CHECK IT:
(5x/3)(x2/4)=5/12
(53/3)(32/4) = 5/12
(2/3)(1/4) = 5/12
common denominator is 12.
(8/12)(3/12) = 5/12
(83/12) = 5/12
5/12 = 5/12
done.
