Answer 2

Answer:

Yes, both values of x for the equations satisfy.

Step-by-step explanation:

a) 3x + 1 = 5x - 1 is the equation. As per the question, put 1 at the place of x.

⇒ (3×1) + 1 = (5×1) - 1
⇒ 3 + 1 = 5 - 1
∴ 4 = 4
Hence verified that x=1 satisfies the equation.

b) 7x = 24 - x is the equation. As per the question, put 3 at the place of x.

⇒ (7×3) = 24 - 3
∴ 21 = 21
Hence verified that x=3 satisfies the equation
