Two equations are given below: a − 3b = 9 a = b − 3 what is the solution to the set of equations in the form (a, b)? (−9, −6) (−4, −3) (−6, −3) (−9, −7)

a − 3b = 9
a = b − 3
we replace a=b-3 for this equation a − 3b = 9 and we have (b-3)-3b=9
or b-3-3b=9
and -2b=9+3
or -2b=12
and we have b=12:(-2)= -6
and a=b-3= -6-3= -9

The answer is (−9, −6)

It creates dogx^2 and then flip your answer and multiply by 2
