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)
x = 6 and y = -2
x=6
3x + 5x = 348x = 34x = 34/8x = 17/4 orx = 4.25
y = 3x 3x + 4y = 30 3x + 4(3x) = 30 3x + 12x = 30 15x = 30 x = 2 y = 3x y = 3(2) y = 6 (2, 6)
-3x + 6 = -30 -3x = -30 - 63x = 36x = 36/3Therefore, x = 12.
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
3x+7=37 -7 -7 3x=30 /3 /3 x=10
x+30 = 3x-50 x-3x = -50-30 -2x = -80 x = 40
4x + 2(3x) = 30 10x = 30 x= 3. Y= 9. (3,9)
Subtract: 3x - 3x - 4y - 2y = 30 - 6 ie -6y = 24 so y = -4 and x = 14/3
