y=2x+9 and y=x+6
Isolate one of the variable using inverse operations. Then solve. Example: 2x + 4y = 0 --subtract 4y>> 2x = -4y --divide by -4>> -1/2x = y --plug in your variable -->>
You cant solve it unless it is an equation. To be an equation it must have an equals sign.
2x + 5 - 5 = 2x. You can not solve for x because this is not an equation.

FOIL stands for First, Outer, Inner, Last. It is the order of operations to solve equations like (2x+3)(3x+2).
You should probably combine like terms. For example, look below for an explanation: 2x - 3 = 4x + 5 + 3 + 3 ----------------- 2x = 4x + 8 -4x -4x ----------------- -2x = 8 ---- --- -2 -2 ------------------ x = -4
In algebra, an identify is an equation which is always true, no mater what value you plug in for the variable. You can recognize an identity because when you solve it, you get out a true statement. Here is an example: 3 + 2x = 3(1+x) - x Distribute: 3 + 2x = 3 + 3x - x Combine like terms: 3 + 2x = 3 + 2x Subtract 2x from each side: 3 = 3 3 = 3 is a true statement, so the equation is an identity.
Solve for y: f(-5)=13+2x
