Question and answer
Solve the system of equations. 4x - 4y = 10 3x + 2y = 5
4x - 4y = 10 divided by 2 on both sides the result is: 2x - 2y = 5 (equ. 1) 3x + 2y = 5 (equ. 2) adding up equations 1 and 2 the result is: 5x = 10 x = 10/5 = 2 4(2) - 4y = 10 -4y = 10 - 8 = 2 y = 2/-4 = -1/2 The solution for the system 4x - 4y = 10 3x + 2y = 5 is (2, -1/2)

4x - 4y = 10 divided by 2 on both sides the result is:
2x - 2y = 5 (equ. 1)
3x + 2y = 5 (equ. 2)
adding up equations 1 and 2 the result is:
5x = 10
x = 10/5 = 2
4(2) - 4y = 10
-4y = 10 - 8 = 2
y = 2/-4 = -1/2
The solution for the system 4x - 4y = 10 3x + 2y = 5 is (2, -1/2)

4x^2+10x-6/2x-1
= 2(x + 3)(2x - 1)/(2x - 1)
= 2(x + 3)

(12x^2 - 10x -12) ÷ (3x + 2)
= (12x^2/3x+2) - (10x/3x+2) - (12/3x+2)
= 4x - 6

(4x^2 - 6x + 8) - (3x^2 - 6x + 2)
= 4x^2 - 6x + 8 - 3x^2 + 6x - 2
= x^2 + 6
