Solve the pairs of equation.  x+y-3.3=0 and 2y-3x-0.6=6
Asked by sakhinafatma055 | 12 Feb, 2020, 09:18: PM
answered-by-expert Expert Answer

x + y - 3.3 = 0 → x + y = 3.3  .... (1)

2y - 3x - 0.6 = 6  → 3x - 2y = - 6.6  ... (2)

Multiply (1) by 2, we get

2x + 2y = 6.6  .... (3)

Adding (2) and (3), we get

5x = 0 → x = 0

Substitute x = 0 in (1), we get

y = 3.3

→ x = 0 and y = 3.3
