Question

X-4/2 = 4x-9/3
A x=-6
B x=-3/5
C x=6/5
D x =6/11

Answer 1

x = 6/5

Explanation:

x-4 4x-9

------ = ----------

2 3

Using cross products

3 * (x-4) = 2 ( 4x-9)

Distribute

3x-12 = 8x-18

Subtract 3x from each side

3x-12-3x = 8x-18-3x

-12 = 5x-18

Add 18 to each side

-12+18 =5x-18+18

6 = 5x

Divide by 5

6/5 = 5x/5

6/5 =x
