Weegy: Solve the system algebraically. Check your work. 5x + 2y = 10 3x + 2y = 6? Asked by Anonymous ...
User: (2x+ y - 10 = 0) (x - y - 4 = 0) What is the value of y? 1/3, 2/3, or 14/3
Weegy: 2x+y-10 = 0
x - y - 4 = 0
===========
3x - 14 = 0
3x = 14
x = 14/3
x - y = 4
14/3 - y = 4
14/3 - 4 = y
14/3 - 12/3 = y
2/3 = y
y = 2/3 source: yahoo
User: Solve the system algebraically. (5x + 2y = 10) (3x + 2y = 6)
Weegy: 5x + 2y = 10.........(i)
3x + 2y = 6..........(ii)
Subtract (ii) from (i), we get
(5x + 2y) -( 3x + 2y)= 10-6
or 2x = 4
hence x= 2
From (i) plugging the value of x, we get
5×2 + 2y = 10
10+ 2y = 10
2y=10-=0
Hence y= 0 source: yahoo
User:
4x - 5y = 3
x = 3 - y
What is the value of x?
9/7
24/14
33/14, or
Weegy: since: X = 3 - Y
Y = 3 - X
since: 4X - 5Y = 3
4X - 5(3 - X) = 3
4X - 15 + 5X = 3
so: 9X = 18
X = 2, Y = 1

User: o hold on i did that wrong
