Answer:
(x,y)=(2,-3)
Step-by-step explanation:
6x+2y=6
7x+3y=5
Multiply both sides by 3
18x+6y=18
7x+3y=5
Multiply both sides by -2
18x+6y=18
-14x-6y=-10
Eliminate one variable by adding the equations
4x=8
x=2
Substitute the value of x to get y
6(2)+2y=6
y=-3
x=2
y=-3
Answer:
y= 12
Step-by-step explanation:
8y x 3(-3y x 2)
By multiplying 3 inside the bracket values
= 8y x -9y x 6
By multiplying the same polynomials co-coefficients
= -72y x 6
y x 6 =72
By Shifting the negative term to the other side
y = 72/6
By dividing
y= 12
The answer is 12 percent change
