Answer:
one solution
Step-by-step explanation:
Well, let's find out by solving the equation! I'll put it below and we can start looking at how to isolate x and see if there is one solution, no solution, or infinite solutions:
[tex]70-10x=-10+40\\[/tex]
First, it's probably a good idea to combine like terms. Both -10 and 40 are like terms on one side of the equation, so we can combine them to get 30. Now our equation looks like this:
[tex]70-10x=30[/tex]
Next, let's subtract 70 from both sides so we can get the x on one side:
[tex]70-70-10x=30-70\\-10x=-40[/tex]
Finally, we can divide both sides by -10.
[tex]\frac{-10x}{-10} =\frac{-40}{-10} \\x=4[/tex]
It looks like there is one solution. Hopefully that's helpful! :)
