Answer:
r=1
Step-by-step explanation:
If you sub r for 1 you'll get 77 as the solution
An example of the difference of squares would be: a^2-b^2 = (a+b)(a-b)
7x + 3y = -12
2x + 5y = 38
5y = -2x + 38
y = -2x/5 + 38/5
7x + 3•(-2x/5+38/5) = -12
29x/5 = -174/5
29x = -174
x = - 6
x=-6
y = -2x/5+38/5
y = -(2/5)(-6)+38/5 = 10
x=-6
y=10
