Justify all steps 9x+31=-23+3x

Step 1: Simplify both sides of the
equation.
9x+31 = 3x - 23
Step 2: Subtract 3x from both sides.
9x+31-3×=3x - 23 -3x
6x+31=-23
Step 3: Subtract 31 from both
sides.
6x+31=31=-23-31
6x =-54
Step 4: Divide both sides by 6.
6x/6 = -54/6
x=-9

x=-9

Step-by-step explanation:

To solve for x you should isolate the variable. Do this by adding, subtracting, and dividing terms from both sides. This is done by using the properties of equality.

1) First, subtract 3x from both sides, so that there is only one variable. You can do this using the subtraction property of equality.

6x+31=-23

2) Next, subtract 31 from both sides to further isolate the variable. This also works through the subtraction property of equality.

6x=-54

3) Finally, divide both sides by 6 to get the final answer. This is allowed through the division property of equality.

x=-9
