Question

solve 3x - 2y = 5 ; 1x + 3y = -4 by cramers rule​

Answer 1

Answer:

x= -1

y= -2

Step-by-step explanation:

5x + 3y = -11 -----( 1 )

x + 2y = -5 ------( 2 )

Multiply 2nd equation by,

so the equation become

5x+10y= -25

multiplying by ( - )

-5x -10y = 25 -------(3) equation

adding eq ( 1 ) and ( 3 )

so we get value y = -2

substitution that value in eq ( 2 )

we get x = -1

Hence we get the value,

x = -1 and y = -2
