Answer:
The solution of system of equation is (-4,-2)
Step-by-step explanation:
The given system of linear equation is
Equation 1: 2x+y=(-10)
Equation 2: 3x+4y=(-20)
Using the Elimination method:
Important step: First multiply equation 1 by 4
we get,
Equation 3: 4(2x+y)=(-40)
Equation 3: 8x+4y=(-40)
Now,
8x+4y=-40 Equation 3
3x+4y=-20 Equation 2
- - +
________
5x+0=(-40)+20
5x=(-20)
x=(-4)
Replacing value of x i any equation
2x+y=(-10)
2(-4)+y=(-10)
(-8)+y=(-10)
y=(-2)
Thus,
The solution of system of equation is (-4,-2)

Step-by-step explanation:
Answer:
(3, 0)
Step-by-step explanation:
(3,6) reflected across the line y=3
y = 3 is parallel to x- axis, the x-coordinate doesn't change and y-coordinate reflects as y - 2*3
- (x, y) → (x',y') = (x, y -2*3)
- (3, 6) → (3, 6 -6) = (3, 0)
<u>Answer is</u> (3,0)
