Ok, what do you need?
ok i have 7x - 9 - 2x = 10 - 3x + 5 Solve
well, you combine like terms, so what are the like terms?
the x es
well let's look at it (7x)+(- 9)+(- 2x) = (10)+(- 3x)+(5) you know that subtraction is adding a negative, so what is the sum of the like terms on the left side of the equation?
close, let's just look at the cooeficients, 7+(-2)
right, now what are the like terms on the right side of the equation.
nothing just the 3x right
well a like term does not have to contain a variable
so 10 and 5 are like terms because they don't have variables. like terms have the same variable, it could be x or nothing at all. x^2 and x are not like terms, but 4x^2 and 8x^2 are, and 3x and 6x are. at the same time 3 and 9 are like terms in an equation
is that too confusing?
yeah kinda but i can go through it
so it will be 15 right
right , so what is the equation with the combined like terms
would it be x= 3
slow down, just put in what you said were like terms
5x and 15
