Answer:
x = -4
Step-by-step explanation:
The solution to a "sum and difference" system of equations can be found by adding the equations together.
(x +y) +(x -y) = (-10) +(2)
2x = -8 . . . . . . simplify
x = -4 . . . . . . . divide by 2

Additional comment
y = -6, though this question did not ask that value.
Answer:
4080cm²
Step-by-step explanation:
I^22 equals to -1 since i^2 is negative one
Answer:
12 outcomes
Step-by-step explanation:
dice = 6 outcomes
coin = 2 outcomes
6 outcomes x 2 outcomes = 12 total outcomes
y=2x+4
that is an equation in slope intercept form where the slope is 2 so you would go up two right 1 and the y intercept would be 4 so (0,4)
