Question

solve each system x-9y=25
6x-5y=3

Answer 1

x-9y=25(*6) 6x-54y= 150 (-) both eq -49y=147
6x-5y=3 6x-5y=3 y=-147/49=3

replace y in the 1st or 2nd eq 6x-15=3
x=18/6=3

Answer 2

x=25+9y
now substitute x in 2nd equation
6(25+9y)-5y=3
150+54y-5y=3
49y=3-150
y=147/49

Answer 3

y=-3
now substitute y value in one of the equation
x=25+9(-3)
x=25-27
x=-2
