Answer:
p = 0
r = 1
Step-by-step explanation:
you can multiply the first equation by -6 to eliminate the 'r' value:
-6(r - 3p) = 1(6)
-6r + 18p = -6
now add the second equation to the new one to get:
17p = 0
p = 0
now find 'r' by setting 'p' equal to zero:
r - 3(0) = 1
r - 0 = 1
r = 1
check:
6(1) - 0 should equal 6; it does
1 - 3(0) should equal 1; it does
