Answer:
C. When you solve for the variable, you will end up with a false statement, like 0 = 2, for an equation with no solution. You will end up with a true statement, like 2 = 2, for an equation with infinity many solutions.
3x + 9 = 10 + x
2x +9 = 10
2x = 1
x = 1/2
Answer:
I dont know sorry so much
You find the variable x or y in one of the lines of the problem and then substitute the value of the variable you first found into the other line of the problem to find the other variable. Then, you plug all of the values you found into either line/equation of the problem to ensure that one side of the equation you pick is equal to what is on the other side of the "=" symbol.
