Question

3/2x-4=2/5+7/10x??

Answer 1

x = 11/2 want me to explain?

Answer 2

yes please

Answer 3

(3/2)x - 4 = 2/5 + (7/10)x --- multiply everything by the common denominator 10
15x - 40 = 4 + 7x -- subtract 7x from both sides
15x - 7x - 40 = 4 -- add 40 to both sides
15x - 7x = 4 + 40 -- combine like terms
8x = 44
x = 44/8 which reduces to 11/2 or as a mixed fraction, it is 5 1/2

Answer 4

multiplying by the common denominator will get rid of the fractions

Answer 5

thank you!

Answer 6

OK So Step 1: Simplify both sides of the equation.


Then Step 2: Subtract 7/10x from both sides.



And Step 3: Add 4 to both sides.
ill just type the rest out
4/5x -4 + 4 = 2/5 + 4
4/5x = 22/5

Last Step 4 Divide both sides by 4/5.
4/5x / 4/5 = 22/5 / 4/5 and you get
x = 11/2
But its either one because you never said you had to reduce it right?
