Please note that <= is meant to be "less than or equal to"...
|4x|+3 <= 2
|4x| <= -1
4|x| <= -1
|x| <= -1/4
No solution. No matter what x is, the absolute value signs will produce some positive number on the left side of the equation. And there is no way for a positive number to be less than or equal to -1/4.
You cannot since it has no solution.
5+y+2y? = 5+3y?
Yes
There is not enough information to solve for x. x+5x+15 must equal something (is it 0?) in order to solve for x.
The two inequalities define a region of the coordinate plane: there is no unique solution.
You cannot since it has no solution.
It can't be solved because the discriminant of this quadratic equation is less than zero
Set it equal to 0 and subtract x and solve for y
15x plus 392 is the answer since you dont have an equal sign
5+y+2y? = 5+3y?
First of all, that's not an inequality. Inequalities have a a less than, equal to, greater than, greater than or equal to, or less then of equal to. But any way, the solution would be this: 3t + 5(-4) 3t+(-20) There you go, hope you liked it!
Add the constants to one side and the x values to the other. You should end up with 8x=16 in which x would equal 2.
x plus 0.068 is not an equation -- it has no equal sign -- so it can't be solved.
Yes
There is one linear inequality in 2 variables: l and x. That is not enough to obtain a solution.
