Question

3s^2 + 2t^2 =11
3s + 2t =1
how to solve with step by step? solution ​

Answer 1

Answer:

t=8/3 or -2

using values of t you can solve for s.

Step-by-step explanation:

from second equation, s=(1-2t)/3

substitute this value into the first equation.

thus, 3(1-2t/3)(1-2t/3) + 2t.t = 11

factorising this equation, you get (3t-8)(t+2)=0

thus, t = 8/3 or -2

substitute value of t in second equation to solve for s.
