x < 5
Let the unknown number be X: -4x-10 = 2 -4x = 2+10 -4x = 12 x = -3 Remember that a minus multiplied by a minus is equal to a plus: -4*-3 = 12
X is less than or equal to 4.
4x + 20
minus 1
x - 2
The equation 7x-12 is less than 4x plus 36 means just what it says7x - 12 less than 4x + 36To solve this, treat it like ordinary algebra and solve for x, replacing the equals sign with the less than sign. Remember that if you multiply or divide by a negative number, then the less than sign flips over and becomes the greater than sign.7x - 12 less than 4x + 367x less than 4x + 487x - 4x less than 483x less than 48x less than 16
This would simplify as 4x-5
7x2 -4x -5x2 +2x = 2x2 -2x
-2x + 6 <= 4x + 18 -2x <= 4x + 12 -12 <= 6x -2 <= x
(2x-1)(2x-1) = 4x^2 -4x + 1
6x - 4y
It is possible.
