x= -.5

here is the mathematical expression, you need an equals sign and something it equals to actually solve for x but I hope this is what you needed or repost with what it equals 4x+4

x2-10 = 4x+11 x2-4x-10-11 = 0 x2-4x-21 = 0 (x+3)(x-7) = 0 x = -3 and x = 7

The easiest way to solve this system of equations is to solve for a variable in one of the equations. In the second equation, y = 3x. This can be substituted into the first equation: y = -4x - 7; 3x = = -4x - 7; 7x = -7; x = -1. Since we have determined that x equals -1, we can then substitute -1 into either equation to find our corresponding y-value. Thus: y = 3x; y = 3(-1) y = -3. Thus, the solution to this system of equations is (-1, -3).

x=2.75 This follows from the equation (4x - 3) + 11 = 19 and 4x = 11

5x + 3 = 4xSubtract 3 from each side:5x = 4x - 3Subtract 4x from each side:x = -3

5+4x-7 = 4x+3-x 4x-2 = 3x+3 4x-3x = 3+2 x = 5

-4x-4 equals -16. Add 4 to both sides; -4x equals -12. Divide both sides by -4; x equals 3.
