I'll quote the question and show the steps underneath that
Take 2x and five and add them together.
2x+5
Divide the result by eight.
%28%282x%2B5%29%2F8%29
Add 3x.
%28%282x%2B5%29%2F8%29+%2B+3x
Subtract the quantity eight times 2x.
%28%282x%2B5%29%2F8%29+%2B+3x+-16x
The result is equal to 100 minus 9x.
%28%282x%2B5%29%2F8%29+%2B+3x+-16x+=+100+-9x
Simplifying %28%282x%2B5%29%2F8%29+-13x+=+100-9x
Multiplying throughout qith 8
2x%2B5+-104x+=+800-72x
Subtracting 5 on both sides
-102x+=+795+-+72x
Adding 72x on both sides
-30X+=+795
Dividing by -30 throughout
X = -26.5
