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.
If a plus sign is missing before the 12, any value greater than or equal to 12.If a negative sign is missing before the 12, any value greater than or equal to -12.
X is less than or equal to 4.
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
Do you mean 4x^4? not understanding the notation. doctor chuck
It can be Equal or Greater than or less than. 4x4 = 16 4x1 = 4 4x-4 =-16
2(4x + 4) = (4x - 12) 8x + 8 = 4x - 12 8x - 4x + 8 = 4x - 4x - 12 4x + 8 = -12 4x + 8 - 8 = -12 - 8 4x = -20 4x/4 = -20/4 x = -5
(2x - 4)/(4x + 5) - 12
-2x + 6 <= 4x + 18 -2x <= 4x + 12 -12 <= 6x -2 <= x
4x + 5 > 7
-64 is 12 more than 4 times a number...-64 equals 12 plus 4 times an unknown number...sounds like an equation to me:-64 = 12 + 4x-64 -12 = 12 + 4x - 12-76 = 4x-76/4 = 4x/4-19 = xThe number you're looking for is -19.
