Question

3x+2y=13,5x-3y=9 solve in substitution method.
​

Answer 1

x=57,y=-79

Step-by-step explanation:

3x+2y=13--------(1)

5x-3y=9---------(2)

from (1) y=13-3x/2 -------(3)

put the value of y in equation 2

5x-3(13-3x/2)=9

10x-39-9x/2=9

10x-39-9x=18

x-39=18

x=18+39

x=57

put the value of x in equation 1

3*57+2y=13

171+2y=13

2y=13-171

2y=-158

y=-79
