Class 8 Linear Equations In One Variable CBSE Questions & Answers

Find the solution of\({\text{2}}x--{\text{ 3 }} = {\text{ 7}}\).

Solve: \({\text{3x }} = {\text{ 12}}\)

Solve \({\text{2}}x--{\text{ 3 }} = x + {\text{ 2}}\)

Solve: \(5x + \frac{7}{2} = \frac{3}{2}x – 14\)

Solve: \(5x - 2\left( {2x - 7} \right) = \left( {3x - 1} \right) + \frac{7}{2}\)

An algebraic equation is an _________ involving variables.

What should be added to twice the rational number\(\frac{{ - 7}}{3}to\;get\;\frac{3}{7}\)?

The difference between two whole numbers is 66. The ratio of the two numbers is 2 : 5. What are the two numbers?

The digits of a two-digit number differ by 3. If the digits are interchanged, and the resulting number is added to the original number, we get 143. What can be the original number?

Solve 2y + 9 = 4.

Solve: 4y = 20

Solve: \({\text{3}}x = {\text{ 2}}x + {\text{ 18}}\)

Solve: \(x = \frac{4}{5}\left( {x + 10} \right)\)

Solve: \(x + 7 - \frac{{8x}}{3} = \frac{{17}}{6} - \frac{{5x}}{2}\)
