Answer:
r = 3[tex]\frac{3}{5}[/tex] and t = 3/5
Step-by-step explanation:
2r+3t=9 ------------------------------------------------(1)
3r+2t=12 ------------------------------------------------(2)
We will first eliminate r, to so that, multiply equation (1) by 3 and multiply equation (2) by 2
6r + 9t =27 -----------------------------------------------(3)
6r + 4t = 24-----------------------------------------------(4)
subtract equation (4) from equation (3)
5t = 3
Divide both-side of the equation by 5
5t/5 = 3/5
t = 3/5
We will now proceed to eliminate t from equation (1) and (2)
To do that, multiply equation (1) by 2 and multiply equation (2) by 3
4r + 6t = 18 ------------------------------------(5)
9r + 6t =36 -------------------------------------(6)
Subtract equation (6) from equation (5)
-5r = - 18
Divide both-side of the equation by -5
-5r/-5 = -18/-5
r = 3[tex]\frac{3}{5}[/tex]
Therefore r = 3[tex]\frac{3}{5}[/tex] and t = 3/5
Answer:
t = 3/5
r= 18/5
