Question

Solve the following pair of linear equations by elimination method:

1) s - t = 3
s/3 + t/2 = 6

2) 0.2x + 0.3y = 1.3
0.4x + 0.5y = 2.3

3) root2x + root3y = 0
root3x - root8y = 0

4) 3x/2 - 5y/3 = -2
x/3 + y/2 = 13/6

Answer 1

that's the 1) bit . hope u understand and do the rest in Ur own , same method
