Twice one number minus a second number is five. Twice the second number plus the first number is eight. Find the numbers. (Points : 5)
unit5a and unit5b
unit5c and unit5d
5 and 5
5 and -3 **Weegy:** 2x - y = 5
2y + x = 8
From the second equation:
x = 8 - 2y
Substitute that into the first equation:
2(8 - 2y) - y = 5
16 - 4y - y = 5
16 - 5 = 4y + y
11 = 5y
y = 11/5
y = 2.2
x = 8 - 2*2.2
x = 8 - 4.4
x = [ 3.6
