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)

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)

2(x - 4) = 6(x + 2)

2x - 8 = 6x + 12

-4x = 20

x = -5

2x - 8 = 6x + 12

-4x = 20

x = -5

(12x^2 - 10x -12) ÷ (3x + 2)

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

= 4x - 6

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

= 4x - 6

x/4+6=10

x/4 = 10 - 6 = 4

x = 16

x/4 = 10 - 6 = 4

x = 16
