Answer & Step-by-step explanation:
[tex]8.5x-6.1=-7.1[/tex]
Add 6.1 to both sides:
[tex]8.5x-6.1+6.1=-7.1+6.1\\\\8.5x=-1[/tex]
Isolate the variable x. Divide both sides by 8.5:
[tex]\frac{8.5x}{8.5} =\frac{-1}{8.5}\\\\ x=-\frac{1}{8.5}[/tex]
Round to the nearest tenth. Simplify division:
[tex]-\frac{1}{8.5}=-0.11764705...=-0.1[/tex]
So, x≈-0.1
