3x-6y=30 y=34-6x
substitute the the value for y from the second equation into the first equation.
3x-6(34-6x)=30
3x-204+36x=30
39x-204=30
39x=234
x=234/39
x=6
Substitute this value of x into equation 2.
y=34-6(6)
y=34-36
y=-2

x=6
Ten. That means 3x equals 30, and 30 divided by three is ten.
3x + 6 = 30 Therefore, 3x = 24 x = 24/3 x = 8
It can be simplified in the form of: 2x3+9x2-7x-34 = 0
4x + 2(3x) = 30 10x = 30 x= 3. Y= 9. (3,9)
