Question

Write 4 solutions
a. 5x – 2y = 10
b. - 4x + 3y = 12
C. 2x + 3y = 24
d. 3x + 4y = 7

Answer 1

ANSWER

1. 5x - 2y = 10

= (5*4) - (3*5)

= 20 - 10

= 10 ( x = 4 , y = 5 )

2. - 4x + 3y = 12

= (- 4*6) + (3*4)

= - 24 + 12

= 12 ( x = 6, y = 4 )

3. 2x + 3y = 24

= (2*6) + (3*4)

= (12) + (12)

= 24 ( x = 6 , y = 4 )

4. 3x + 4y = 7

= (3*5) + (4*-2)

= (15) + (-8)

= 7 ( x = 5 , y = - 2 )
