Answer:
D. (17,-1)
Step-by-step explanation:
We'll start by canceling out x. To do so, multiple the first equation by -1
-1( x - 2y)=( 19 )(-1)
This gives us:
-x +2y = -19
x + 3y = 14
Add the equations together:
→ 5y = -15
→ y = -1
Plug in y = -1 into an equation:
→ x + 3(-1) = 14
→ x - 3 = 14
→ x = 17
(17,-1)

Step-by-step explanation:
Answer:m =-1
Step-by-step explanation:
To solve m=-(4+m)+2
Open the brackets
m=-4-m+2
Collect like terms
m+m=-4+2
2m=-2
Divide through by -2
m=-1
