Question

2.
(x, y)|(3, 0) 0 (0, 3)
Solve the following simultaneous equ
(1) x + y = 6 ; x - y = 4
(3) x + y = 0 ; 2x - y = 9
(5) 3x - 4y = -7 ; 5x – 2y = 0
​

Answer 1

Step-by-step explanation:

x+y=6........(1)equation

x-y=4.........(2)equation

Let's adding the equation (1)from (2).

x+y=6..... (1)

x-y=4......(2)

2x+0=10

2x=10x=2÷10

x=5

Let's place the value x=5 in equation(1)

5+x=6

y=6-5

y=1

Solutions (x,y)=(5,1)
