If 5x=-20 then it would be
adding 2 and subtracting 2 they cancel out so its
and if you subtract 2 from negative 18 it is negative 20 so it is true
On a cube, you have 6 faces, therefore you have 1 chance to get 6 and 5 chances not to get 6.
Therefore, the overall probability not to get 6 is 5/6 = 0.8333
If you roll the cube 18 times, the prediction of unsuccessful rolls will be:
18 × 0.8333 = 15
Therefore, you expect to have 15 unsuccessful rolls over 18 total rolls.

2x - 4y = 32
2x - 8y = 48
2x - 2x - 4x - (-8y) = 32 - 48
4x = -16
x = -16 ÷ 4
x = -4
substitute your value of x into any of the original equations
2 (-4) - 4y = 32
-8 - 4y = 32
-4y = 32 + 8
-4y = 40
y = 40 ÷ -4
y = -10
