Equation 1: 8x+2y=308x+2y=30
equation 2: 7x+2y=247x+2y=24
which variable pair should we try to eliminate?
the x's because the coefficients are the same.
the y's because the coefficients are the same.
the x's because the coefficients are different?
the y's because the coefficients are different?
now that we've eliminated the variable pair, what is the resulting equation?
15y+4y=5415y+4y=54
x+4y=54x+4y=54
4y=64y=6
consider the following system of equations:
equation 1: 8x+2y=308x+2y=30
equation 2: 7x+2y=247x+2y=24
what is the solution to the system?
(6,8)
(6,-9)
(1,11)
(0,12)
