Answer:
4) (-3 , 2)
Step-by-step explanation:
The values of x and y that satisfy this system of equations are 10 and 5 respectively
<h3>Simultaneous equation</h3>
Given the system of equations
x + y = 20
3x - 3y = 30
_____________________
x + y = 20
x - y = 10
Add the equations
2x = 20 + 10
2x = 30
x = 30/2
x = 15
Substitute
x -y = 10
15 - y = 10
y = 5
Hence the values of x and y that satisfy this system of equations are 10 and 5 respectively
