I had been asked this question in unit test.

Asked question is from Reduce the Linear Equation and Find the Value of the Variable in section Linear Equations in One Variable of Mathematics – Class 8

Answer 1

Correct answer is (a) \(\frac{-1}{2}\)

Explanation: 3(x – 3) = 5(x + 2)

∴3x – 9 = 5x + 10

∴3x – 5x = 10 – 9

∴-2x = 1

∴x = \(\frac{-1}{2}\).
