2x+2y=-10
-x+y. = 9
2x + 2y = -10
-2x + 2y = 18
4y = 8
y= 2
2 - x = 9
-x = 7
x = -7
Answer:
2nd degree
Step-by-step explanation:
If you would like to solve the equation 2 - 3 * x = 8 for x, you can calculate this using the following steps:
2 - 3 * x = 8
-3 * x = 8 - 2
-3 * x = 6 /(-3)
x = 6 / (-3)
x = -2
Result: x equals to -2.
Answer:
# 2 the you are on the right one
Step-by-step explanation:
For A B and C, you just plug in the given number
A

B

C

And for D, you set the equation to 26 and solve for n

I had to use x instead of n, but for D n=7. :)
