Your answer is -5.
This is because, if you expand the single bracket, you get -6x -3a, and since the other side of the equals sign is -6x + 15, then you need to do 15 ÷ -3 = -5.
I hope this helps!
I showed my work and answer in this picture. When simplifying square roots you can split them into a perfect squares root time the remainders
11/12 of 7 is simply their product.

8x-2 is the answer because 4x2=8
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
Hope this helps you
