Answer 2

`\huge\boxed{\sf {(5,2)}}`

Explanation:

Given equations:

6x - 3y = 24 ----------------(1)

8x + y = 42 -----------------(2)

Take Eq. (1)

6x - 3y = 24

• Take 3 as a common factor

3(2x - y) = 24

• Divide both sides by 3

2x - y = 24/3

2x - y = 8 ----------------(3)

• Add Eq. (2) and (3)

8x + y + 2x - y = 42 + 8

8x + 2x = 50

10x = 50

• Divide both sides by 10

x = 50/10

x = 5

• Put x = 5 in Eq. (3)

2(5) - y = 8

10 - y = 8

• Add y to both sides

10 = 8 + y

• Subtract 8 from both sides

10 - 8 = y

2 = y

y = 2

Solution set:

{(x,y)} = {(5,2)}

`\rule[225]{225}{2}`
