Question

solve the following equation by elimination and cross multiplication method. 3x+y=7, 4x+5y=14..pls do stp by stp​

Answer 1

3x + y = 7 , 4x + 5y = 14

3x + y = 5

x= 1÷3 ( -y+7)

x= -1÷3y +7÷3

4 [ -1÷3 y + 7÷3 ] +5y = 14

-4÷3y + 28 ÷ 3 + 5y = 14

11÷ 3 y = 14 ÷ 3

y = 14 ÷ 11

x = -1÷3 × (14÷ 11)+7÷3

x = 21 ÷11

x = 14 ÷ 11
