Linear Equations in One Variable — NCERT Class 8 Mathematics Important Questions & Revision Notes

A linear equation in one variable is an equation in which the highest power (degree) of the variable present in the equation is 1.

Transposing $-2$ to the RHS: $x = 7 + 2 = 9$.

Transposing $3$ to the RHS: $y = 10 - 3 = 7$.

Dividing both sides by 6: $x = \frac{12}{6} = 2$.

Multiplying both sides by 5: $x = 10 \times 5 = 50$.
