A pair of equations is shown below:
1 answer:
I would use subsitution because both are already equal to a single variable
set both equal since both equal y
8x-9=y=4x-1
8x-9=4x-1
minus 4x both sides
4x-9=-1
add 9 boh sides
4x=10
divide by 4
x=10/4=5/2
sub for x
y=4x-1
y=4(10/4)-1
y=10-1
y=9
(5/2,9) is solution
A. work shown above
B. (5/2,9) or (2.5,9)
