Answer:
14=3y - x ----------- 1. 20=2y - 3x -------------2.
x= 14 - 3y --------- 3.
Putting eq 3.in eq 2.
=>20 = 2y - 3(14 - 3y)
=>20 = 2y - 42 + 9y
=>20 + 42 = 11y
=>62 = 11y
=> y = 62/11
Putting y = 62/11 in eq 1.
=> 14 = 3(62/11) - x
=> 14 = 186 - 11x/11
=> 11x = 186 - 154
=> x = 32/11
Hope this helps you ♥️
