Answer:
The value of x is -5 1/6.
Step-by-step explanation:
You must isolate the variable in order to solve equations with variables.
Isolating variable is basically when you divide, multiply, add, or subtract to put a variable on ONLY one side of the equation.
-31 = 4x + 1x + x Combine like terms
-31 = 6x Divide 6 on both sides
-31/6 = x
Or in a mixed number, -5 1/6
