t=1
r=1
Step-by-step explanation:
10r-4t=6 equation 1
7r + 5t=12 equation 2
using equation 1 we have:
10r-4t=6
10r = 6+4t
r = (6+4t) / 10 equation 3
using equation 3 in equation 2 we have:
7 ((6+4t) / 10)) + 5t=12
4.2 + 2.8t + 5t = 12
7.8t = 12-4.2
7.8t = 7.8
t = 7.8/7.8
t=1
so we have:
r = (6+4 (1)) / 10
r = 10/10
r=1
