First let's get rid of the parenthesis:
12 - 4x + 3x = 4 + 10 + 2x
Now group the x's on the left and the numbers on the right
-4x + 3x - 2x = 4 + 10 - 12
...and simplify
-3x = 2
divide by -3 to isolate x
x = -2/3
x=3/2-1/4
8x+2y=12
move the variable to the right side and change the sign.
8x=12-2y
divide both sides of the equation by 8
x=3/2-1/4y
the final solution is
x=3/2-1/4y
Answer:
1/11
Step-by-step explanation:
12 + 8 + 2
22 / 2
1/11

Answer:
Step-by-step explanation:
3) Sales tax rate = ![\frac{42.42}{499}*100](https://tex.z-dn.net/?f=%5Cfrac%7B42.42%7D%7B499%7D%2A100)
= 8.50
= 9%
4) Rate of commission = ![\frac{1400}{28000}*100](https://tex.z-dn.net/?f=%5Cfrac%7B1400%7D%7B28000%7D%2A100)
= 5 %
5) Reduction = ![\frac{30}{100}*5000](https://tex.z-dn.net/?f=%5Cfrac%7B30%7D%7B100%7D%2A5000)
=$ 1500
New price = 5000 - 1500
= $ 3500
