Solve for 2x+1=-15-2x
I am really confused with how to solve this
problem, please help!
What you need to do is get all the x terms on
the left side of the equation, and all the constants
on the right side. Remember that as long as we
perform the same operation on both sides of the
equation, we still have an equation, i.e., both
sides remain equal, even though the value has
changed.
2x + 1 = -15 - 2x
On the right side, 2x is being subtracted. Add
2x to both sides of the equation.
2x + 1 + 2x = -15 - 2x + 2x
On the right side, the 2x terms cancel out. On the
left side, go ahead and add the x terms.
2x + 1 + 2x = -15
4x + 1 = -15
We want to remove the constant (1) from the
left side, so subtract 1 from both sides.
4x + 1 - 1 = -15 - 1
Perform the operations.
4x = -16
The final step is to divide both sides by 4.
4x / 4 = -16 / 4
x = -4
