Check wheather the equality of the equation in maintained or not, by putting the value of the given variable written next to the equation below.
X = -5 can this be expressed as a linear equation in two variables?
True
False
Select the correct approach for solving a pair of linear equations in 2 variables by elimination method. i) Add or subtract one equation from the other so that one variable gets eliminated. ii) Multiply both the equations by any non-zero constant to make the coefficients of one variable (either x or y) numerically equal. iii) Solve the equation in one variable (x or y) to get its value. iv) Substitute the value of x (or y) in either of the original equations to get the value of the other variable.
