Answer:
<h2>x = - 1.106</h2>
Step-by-step explanation:
0.3(10-5x)=31.5(8x+9)
<u>Expand the terms in the bracket</u>
That's
3 - 1.5x = 252x + 283.5
<u>Subtract 3 from both sides</u>
3-3 - 1.5x = 252x + 283.5 - 3
-1.5x = 252x + 280.5
<u>Subtract 252x from both sides</u>
That's
- 1.5x - 252x = 252x - 252x + 280.5
- 253.5x = 280.5
<u>Divide both sides by -253.5</u>
We have the final answer as
x = - 1.106
