Answer: 30+4x
Step-by-step explanation: Expanding the expression you would get 30+6x-2x and then you subtract the 6x and 2x to get 4x
Step-by-step explanation:
6x+5y=25 .......eq1
or, 6x+5y-25=0
or,6x-25= -5y
or, 6x-25/5=y
or, 6x-5=y ......eq2
putting value of y in,
6x+5y=25 eq1
or, 6x+5(6x-5)=25
or, 6x+30x-25=25
or, 36x = 50
or, x=50/36
and x = 25/18
putting x value in,
6x-5=y eq2
6×25/18 -5 = y
10/3 = y
