Sagot :

Answer:

s = ½

t = -2

Step-by-step explanation:

4s - 3t = 8 (equation 1)

2s + t=-1 (equation 2)

4s - 3t = 8 (equation 1)

4s + 2t = -2 (equation 2)

Using Elimination Method:

4s - 3t = 8

- 4s + 2t = -2

___________

-5t = 10

t = -2

Substituting the value of t to one of the equations above:

4s - 3t = 8

4s - 3(-2) = 8

4s + 6 = 8

4s = 2

s = ½
