Question

Solve the following system using the SUBSTITUTION method. x - 3y = 2 2x - 6y = 6

Answer 1

ANSWER:

• x – 3y = 2 ...(1)
• 2x – 6y = 6 ...(2)

On solving eq(1), we get

• x – 2 = 3y
• x – 2/3 = y

Plug the value of x in eq(2)

• 2x – 6(x - 2/3) = 6
• 2x – 2(x – 2) = 6
• 2x – 2x + 4 = 6
• 0 = 6 – 4
• 0 ≠ 2

So, given system of equations is not correct.

Answer 2

Step-by-step explanation:

x - 3y = 2

x=2+3y.....(1)

2x - 6y = 6

2(2+3y)-6y=6

it is not measurable.
