First multiply the given equations by suitable numbers so as to make the coefficients of one of the unknowns, numerically equal
Now add the new equations, if the numerically equal coefficients are opposite in sign, otherwise, subtract them.
The resulting equation is linear in one unknown. Solve it to obtain the value of one of the unknowns.
Substitute the value of this unknown in any of the given equations. Solve it to get the value of the other unknown.
Solve the given systems of linear equations by elimination method: 4x – 18 = 3y, 6x + 7y – 4 = 0.
Adding (iii) and (iv). => 46x = 138.
So this will be => 46x = 138
So x = 3
The solution is x = 3 and y = -2.
