2x-11
9y2+66y+121 = (3y+11)(3y+11) when factored
2x + 3y = 11Subract 2x from each side:3y = 11 - 2xDivide both sides by 3:y = 11/3 - (2/3)x
It can't be answered. You need the same variables on both sides. Example: 3y+5x=5 1/2 x (etc.)
x = 5, y = -1
2x-11
9y2+66y+121 = (3y+11)(3y+11) when factored
Collect like terms: 2x + 3y + 3y - 5 - 6 2x + 6y - 11
How do you add 2x plus 3y equals 18 in 5x-y equals 11
16x2 + 8x + 1 - 9y2 = (4x + 1)2 - (3y)2 which is a difference of two squares. = (4x + 1 + 3y)*(4x + 1 - 3y)
y=-3-3 times -3= 9, 9+11= 20.-3y + 11 =20subtract 11 from each side, then -3y = 9divide each side by -3, then y = -3
Solve the equations by moving the variable to one side : 7y + 11 = 3y + 25 (subtract 3y from each side) 4y + 11 = 25 (subtract 11 from each side) 4y = 14 Y = 3.5
(10,13)
3y +3y = 6y
2x + 3y = 11Subract 2x from each side:3y = 11 - 2xDivide both sides by 3:y = 11/3 - (2/3)x
3y + 4z + 12y = 3y -3y -3y ------------------------- 4z + 12y = 0 divide everything by 4 z + 3y = 0 -3y -3y z = -3y
