-3(2x-6)=42,-6x+18=42,-6x=24,x=-4

- 3 (2 x - 6) = 42, - 6 x + 18 = 42, - 6 x = 24, x = - 4

x = - 4

Solution steps

- 3 (2 x - 6) = 42 - 6 x + 18 = 42 - 6 x = 24 x = - 4

Substitute

x = - 4

- 3 (2 (- 4) - 6) = 42 - 6 (- 4) + 18 = 42 - 6 (- 4) = 24

Simplify

42 = 42 42 = 42 24 = 24

The solutions to the system of equations are:

x = - 4

x + 1 = 3, x + 2 = x + 2

2 x + 3 y = 15, 4 x + 6 y = 24

4 x - 3 y = 5, 8 x + 6 y = 10

2 x + 7 y = 20, 3 x - 7 y = 4

7 p - 52.41 p = 63, r = 3
