Solve using elimination
8x - 3y = -6
-8x + 7y = -18
( ___ , ___ )

x= -3

y= -6

Step-by-step explanation:

8x - 3y= -6 equation 1

-8y + 7y= -18equation 2

Using elumination method

Multiply equation 1 by -8 and multiply equation 2 by 8

-64x + 24y = 48

-

64x + 56y =-144

-32y = 192

y = 192/-32

y= -6

Substitute -6 for y in equation 1

8x - 3(-6) = -6

8x + 18= -6

8x= -6 -18

8x=-24

x= -24/8

x= -3

Hence x = -3 and y = -6

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
