Question

By equating coefficients of variables, Solve the following equations. x - 2y = - 10 ;
3x - 5y = -12

Answer 1

Step-by-step explanation:

x = -10 + 2y.

putting value of x in 2nd equation

3(-10+2y) -5y = -12

-30 + 6y -5y = -12

-30 +y = -12

y = 18

putting value of y in first equation

x - 2(18) = -10

x - 36 = -10

x = -10 + 36

x = 26

verifying the answer

putting both values in first equation --

26 - 2 (18) = -10

26 - 36 = - 10

-10 = -10

hence the values of x is 26 and y = 18
