Answer:
Step-by-step explanation:
1,)
3x+y=4 <-Equation 1
2x-y=6 <-Equation 2
Step 1 Eliminating Y Multiply negative both side
-[3x +y = 4 ] -
-3x-y = -4 <-Equation 3
Equation 2 to Equation 3
2x-y=6
-
-3x-y = -4
= 5x = 10
x =2
Substituting X to Equation 1
3x+y=4
3(2) + y =4
6 + y = 4
y = -2
Therefore x =2 and y = -2
Answer:what does that mean?
Step-by-step explanation:
Systems of equations is the system that equations go in
Using the quotient, [f(-4)-f(1)]/(-4-1)=(4--1)/(-4-1)=5/-5=-1 is the average rate of change over [-4,1]
