What is
x=8
What is the value for x that makes the equation true:
2x+x+3x+4x=10
x=1
What is the solution to the equation
2x+3 = x+5
x=2
The inverse of addition
What is SUBTRACTION
Mr. Analla solved the equation and said no solution. Was he correct?
4(x-2)+3x=5x+11+x-3+x
4x-8+3x=5x+11+x-3+x
7x-8=7x-8
-8=-8
No this solution is infinite

Solve for x
2x+2x+2x-4x+3=-5
x=-4
Alan wanted an 90 average on his test if he scored a 95 and 85 on the last two tests what does he need to get on the next to have a 90 average?
(95+85+x)/3=90
x=90
What is the inverse operation needed to solve this equation
3x=12
What is DIVISION
This solution means that no matter your answer you will have an equation that is always true.
Infinitely many solutions
Infinite

x/2+3=5
What is Multiplication and Subtraction
Ms. Christy solved the equation and said infinitely many solutions. Is she correct?
2(x-2)+x=5x-5+1-2x
4x-4+x=7x-5+1-2x
5x-4=5x-4
-4=-4
Yes she is correct, the statement is true therefore infinitely many solutions.
