Oh, dude, that's like basic math, but sure, I'll help you out. So, 7x + 4x equals 11x. It's like adding up all the x's in the neighborhood and getting 11 of them. Math can be fun, right?

12x2 + 7x + 1 = 12x2 + 3x + 4x + 1 = 3x*(4x + 1) + 1*(4x + 1) = (4x + 1)*(3x + 1)
7x-3=3x+8 7x-3x=8+3 4x=11 x=11/4=2.75
7x-4 = 3x+36Add 4, it cancels out.. So,7x = 3x+40Now subtract 3x from 7x..4x = 40..40 divided by 4 is 10So, X= 10
x2+11x+11 = 7x+9 x2+11x-7x+11-9 = 0 x2+4x+2 = 0 The above quadratic equation can be solved by using the quadratic equation formula and it will have two solutions.
Here's the kind of process you can use to find out:Write the equation, so you can look at it:7x + 2 = 4x - 3Subtract 4x from each side of the equation:3x + 2 = -3Subtract 2 from each side:3x = -5Divide each side by 3:x = - 5/3
