How do you solve #-10+x+4-5=7x-5#?
First, you gather all the "x" terms on one side of the equation;
and all of the constants on the other side of the equation.
1st: subtract x from both sides of the equation.
(We want to move the x over to the right-hand side, so we do the opposite operation on x. X is positive on the left, so we subtract, and we have to do the same thing to both sides of an equation.):
You then have:
All the x's are now on the right-hand side of the equation.
Now combine the constants on the left side of the equation:
so we have:
There is one more constant to move, so add it to both sides:
Let's write it as:
Now we need to divide both sides by - 6 in order to end up with only one x:
Since we want to know what positive x is, we now multiply both sides of the equation by
which is the answer.
Now check by plugging
Do both sides add up to negative 12? They should.
