User: Solve the system algebraically. 2x+ y - 10 = 0 x - y - 4 = 0 What is the value of y? 1/3 2/3 14/3

Weegy: The solution for 2x+y-10=0, x - y - 4 = 0 is x = 14/3 ,y = 2/3.
From 2x + y - 10 = 0 ,we can get y = 10-2x
put y= 10 - 2x into the 2th equation
x - y - 4 = 0
x -(10 -2x) - 4 = 0
3x = 14
x =14/3

y= 10 -2x
y= 10 - 2*14/3
y= 2/3


User: Solve the system algebraically. 4x - 5y = 3 x = 3 - y What is the value of x? 9/7 24/14 33/14

4x - 5y = 3
x = 3 - y
substitute x in the first equation the result is:
4(3 - y) - 5y = 3
12 - 4y - 5y = 3
-9y = 3 - 12 = -9
y = -9/-9 = 1
x = 2
The value of x is 2.

5x = 10 is the result of adding the system of equations: 2x + y = 4 3x - y = 6 .
2x + y + 3x - y = 4 + 6
5x = 10
