(2x - 3)/4 - 3x/2 = 2x-18
Multiply by 4 to remove denominators:
2x - 3 - 2*3x = 4*(2x-18)
2x - 3 - 6x = 8x - 72
12x = 69
x = 69/12 = 5 3/4

(2x-3)/4 - 3x/2 = 2x -18 => multiply by 4 => 2x-3-6x = 8x-72 then slove for x, x = 69/12 = 23/4

multiply (3x/2) by 4 to make like denominators =6x/4
subtract both fractions (2x-3)/4 - (6x/4)
(-4x-3)/4= 2x-18
multiply 4 to both sides to get rid of denominator
-4x-3=8x-72
bring x on one side and numbers on other
-12x=-69
x=69/12
x=23/4
ps Julie J
im in 7th grade too...

2x-3/4 - 3x/2 = 2x -18
(2x-3-6x)/4=2x-18
-4x - 3 = 8x - 72
69 = 12x
x = 69/12
= 5.75

let us see: ( 2x-3/4)-(3x/2)=2x-18 so 2x-3/4-6x/4=2x-18 so
-4x-3=8x-72 so 69=12x x=69/12

(2x-3)/4 - 3x/2 = 2x - 18
Multiplying both sides of this equation by 4:
(2x - 3) - 4(3x/2) = 4(2x - 18)
2x - 3 - 6x = 8x - 72
-4x - 3 = 8x - 72
69 = 4x
x = 69/4
