Answer:
x = - 1.106
Explanation:
0.3(10-5x)=31.5(8x+9)
Expand the terms in the bracket
That's
3 - 1.5x = 252x + 283.5
Subtract 3 from both sides
3-3 - 1.5x = 252x + 283.5 - 3
-1.5x = 252x + 280.5
Subtract 252x from both sides
That's
- 1.5x - 252x = 252x - 252x + 280.5
- 253.5x = 280.5
Divide both sides by -253.5
We have the final answer as
x = - 1.106
Hope this helps you
