Answer:
x = 1/3
Step-by-step explanation:
8x –3(5x–2)=7–10x
Distribute
8x - 15x +6 = 7-10x
Combine like terms
-7x + 6 = 7- 10x
Add 10x to each side
-7x +10x+ 6 = 7- 10x+10x
3x+6 = 7
Subtract 6 from each side
3x+6-6 =7-6
3x = 1
Divide each side by 3
3x/3 = 1/3
x = 1/3
Answer: x = 1/3
Step-by-step explanation: Start by changing the -3 to plus a negative 3 so you know that you are distributing a -3 through the parentheses.
-3(5x) is -15x and -3(-2) is 6.
So we have 8x - 15x + 6 = 7 - 10x.
Simplifying the left side further gives us -7x + 6 = 7 - 10x.
Now subtract 6 from both sides to get -7x = 1 - 10x.
Now add 10x to both sides to get 3x = 1.
From here it should be easy to find that <em>x = 1/3</em>.

Answer:
x=8/21
Step-by-step explanation:
(3/4)/(2/7) = 1/x
(3/4)x = (2/7)
x = (2/7) / (3/4)
x = (2/7) * (4/3)
x = 8/21
