X+y=3<br> y+x= 5<br><br> help please
Oksana_A [137]
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

2t + j = 80
3(0.5)t + 2(0.5)j = 70

j = 80 - 2t
1.5t + j = 70
1.5t + 80 - 2t = 70
-0.5t = 70 - 80
-0.5t = -10
t = -10/-0.5
t = 20

j = 80 - 2t
j = 80 - 2(20)
j = 80 - 40
j = 40

so ur answer is C
