3x/4-2x/3=1/2

Question

I need more answers

12/x+5/y=8

8/x-3/y=-1

Answer 1

Hi so I think if this is you question: 3x/(4-2x)/3 = (1/2), then solving for x:

1.)Multiply both sides by 3, giving you

• 3x/(4-2x)= 2/3
• Break down: multiplying the left side of the equation removes the 3. (1/2)*3 = 2/3

2.) Now you have 3x/(4-2x)= 2/3 so you can cross multiply to keep things simple, giving you

• 6x= 12-6x
• Break down: 2 * 3x = 6x also, (3 * 4) + (3*-2x) = 12-6x

3.) Now you have 6x= 12-6x so you combine like terms giving you

• 12x = 12x 
• Breakdown: take 6x from right and move to left by subtracting it

4.) Finally you have 12x = 12x, so you divide both sides by 12

• x = 1
• Breakdown: 12/12 equals 1

Hope this helps!
