Question

Equate the co-efficient of one of the variable, for the given equations...

a) 5m – 3n = 19; 4m + 5n = 13

b) 3a + 5b = 22; 6a + 7b = 9​

Answer 1

Step-by-step explanation:

By equating coefficients of variables, solve the following equations.

(i) 3x−4y=7;5x+2y=3

(ii) 5x+7y=17;3x−2y=4

(iii) x−2y=−10;3x−5y=−12

(iv) 4x+y=34;x+4y=16
