Let’s ReviewA Common Mistake
Thinking that your math is wrong if both sides of the equation are not
equal

Let’s ReviewCore Lesson
What is the solution of x+1=x?
X + 1 = X-X = -X
1 = 0No Solution

Let’s ReviewCore Lesson
How many solutions does this equation have?
2x + 7 + 5x = 7(x+8)7x + 7 = 7x + 56
-7x = -7x 7 = 56 No Solution
