Answer:
x=(-13/5), y=(-6/5)
Step-by-step explanation:
I will do step by step since I dont see a picture.
when you add them it gets rid of the y,
5x=-13
divide out the 5
x=(-13/5)
plug this into the first equation
2(-13/5)-y=-4
-5.2-y=-4
add 5.2 to each side
-y=1.2
divide out the negative
y=-1.2 or (-6/5)
Solve by elimination ie eliminate x or y from the equations by performing operations on them.
first label the equations , to follow the process.
x - y = 5 ----------------(1)
x+ y = 3 ----------------(2)
If (1) and (2) are added then y will be eliminated.
(1) + (2) gives : 2x = 8 → x = 4
now substitute this value of x into either of the 2 equations and solve for y.
let x = 4 in (1) : 4 - y = 5 → -y = 1 → y = -1
check in (1) : 4-(-1) = 4+1 = 5
check in(2) : 4 - 1 = 3
So your answer is x = 4 , y = -1
y=-1x+4

hope it helps
sorry I had no idea how to explain
Answer:
2
Step-by-step explanation:
Into f (x) = x - 4, plug 5 in the place of x: 5 - 4 = 1
Into g (x) =6 - x, plug 5 in the place of x: 6 - 5 = 1
Then: 1 + 1 = 2
