Answer:
x = 13.5 and y = 7
Step-by-step explanation:
Given equations are :
x + y = 20.5 ...(1)
x − y = 6.5 ...(2)
Add equation (1) and (2).
x + y + x- y = 20.5+6.5
2x = 27
x = 13.5
Put the value of x in equation (1).
13.5 + y = 20.5
y = 20.5-13.5
y = 7
Hence, the values of x and y are 13.5 and 7.
Answer:
x=-2
y=8
Step-by-step explanation:
4x+2y = 8
4x+3y = 16
Subtract the first equation from the second equation
4x+3y = 16
-4x -2y = -8
---------------------------
0x +y = 8
y =8
Substitute this into the first equation to find x
4x+2(8) = 8
4x+16 = 8
Subtract 16 from each side
4x+16-16 = 8-16
4x = -8
Divide each side by 4
4x/4 =-8/4
x =-2
