3x = 2x ( alternate exterior angel)
3x - 2x = 0
x = 0
Answer:
x <-14.5
Step-by-step explanation:
2x + 2(x+5) <+4(8 – 20)
Distribute
2x+2x+10 < 4 (-12)
4x +10 < -48
Subtract 10 from each side
4x+10-10 <-48-10
4x< -58
Divide each side by 4
4x/4 < -58/4
x <-14.5
Step-by-step explanation:
c is the correct answer
Put the problem into a proportion to make it easier to solve.
32 x
=
16 100
You can use cross products to simplify this proportion. Multiply 32 by 100, and set that number equal to 16 *x.
Your equation should now look like this
3200=16x
You are trying to get the variable alone on one side, so you should divide both sides by 16.
If this is performed correctly, then your final answer should be
x=200.

I gotchu.
<span>3x-9x+6=20-3x+4x
Combine like terms.
-6x+6=20+x
Bring x over to the left side.
-x -x
-7x+6=20
bring 6 to the right side.
-6 -6
-7x=14
Divide -7 on both sides to isolate x.
x= -2
