Answer:
x=7/2
Explanation:
First, distribute the 9 on the left side
9(3-2x)=2(10-8x)
(9*3)+(9*-2x)= 2(10-8x)
27-18x= 2(10-8x)
Next, distribute the 2 on the right side
27-18x=(2*10)+(2*-8x)
27-18x=20-16x
Now, move all the numbers to one side of the equation, and the variables to the other.
27-18x=20-16x
Add 18x to both sides
27-18x+18x=20-16x+18x
27=20+2x
Subtract 20 from both sides
27-20=20-20+2x
7=2x
Now all the variables are on one side, and the numbers are on the other. x is still not by itself. It is being multiplied by 2. To undo this, divide both sides by 2
7/2=2x/2
7/2=x
