Add 4x + 2x = 6x + 4 = 6x + 4
Yes.
8x + 15
They are all the points on or above the line [ y = -2x + 20 ]. There are a lot of them.
4x + 5 >= 11.... subtract 5 from both sides and divide by 4.
Add 4x + 2x = 6x + 4 = 6x + 4
Yes.
8x + 15
They are all the points on or above the line [ y = -2x + 20 ]. There are a lot of them.
-4x + 2 = 6 -4x = 6 - 2 -4x = 4 x = 4 / -4 x = -1
4x + 5 >= 11.... subtract 5 from both sides and divide by 4.
An inequality requires an inequality sign, usually "less than", "less-than-or-equal", "greater than", or "greater than or equal". Assuming one of these inequality signs is between the "4x" and the "12", for example: 4x < 12, just divide both sides by 4. Just as when you solve equations, the idea is to isolate the variable on one side.
the solution for the inequality 4x + 2 - 6x < -1 was x < 3/2
4x + 7 is an expression, not an equation. Only an equation (or an inequality) can have solutions, an expression cannot have a solution.
It is an algebraic expression in the form of: 4x+32
6x
6x + 5
