Step-by-step explanation:
First we distribute the 4 amongst everything inside the parentheses.
(Remember that when we distribute numbers, we are basically multiplying them.)
So now we have: 4x - 856 = -3.7
Next we do: 856 + (-3.7), and that gives us 852.3
Finally, we divide both sides by 4 in order to isolate the x-value.
Our answer is now x = 213.075
Hope this helps you :)
