Answer:
21x+4
Step-by-step explanation:
X’s: 21x
#’s: 4
So it will be 21x+4
Answer:
200$
Step-by-step explanation:
5x20=100 plus 100 from annual
4 x^2 - 32 = 8x
-8x -8x
4x^2 - 8x - 32 = 0
Factor the expression ...
4 ( x+2) ( x - 4) = 0
Set the factors equal to 0 ...
x + 2 = 0 x - 4 = 0
-2 -2 +4 +4
x = - 2 or x = 4
2 step equations are equations that require 2 steps to solve it.
For example, 2x + 5 = 3x + 6
To solve for x, we must isolate it.
First subtract 2x on both sides, which is ONE step.
2x + 5 = 3x + 6
-2x -2x
5 = x + 6
The we must subtract 6 from both sides of the equation, which makes is the second step.
5 = x + 6
-6 -6
-1 = x
-1 would be the answer and we only used 2 steps to solve it.
