3x² + 3y² = 75

no, 4x-3y=11x 3x-5y doesn't equal -11

2x + 3y = 17 3x + 4y = 24 (2x + 3x) + (3y + 4y) = (17 + 24) 5x + 7y = 41

The slope is -1. 3x+3y=12 Subtract 3x 3y=-3x+12 Divide by 3 y=-x+4

No.

x = 2.15 and y = 3.75

70000000y=35t

2x+3y=13 3x-y=3 x=2

y=-2/3x

Multiply first equation by 1.5, giving 3x + 3y = 12, but we are told that 3x + 3y = 6. If there isn't an error in the question then 2 = 1!

(5, 1)

(-1, 0)

(4, 5)

(2, 2)

solve -3x-3y=-15

(14x-2y)+(7x-3y)+(-3x) = 14x-2y+7x-3y-3x =(14+7-3)x-(2+3)y =18x-5y

it is equal to 6y plus y

You need to organise your question properly. 3x+2y=4 4x + 3y= 7? Is 4 4x = 44x or 4-4x or 4+4x How can there be 2 equal signs in 1 equation?

There is not an answer but you can factor it.3x+3y=3(x+y)

No, the two lines are not perpendicular.

All that can be deduced is that x + y = 14.

x = 5, y = -1

x = 3 and y = 2

{-4,-5}

Collecting like terms they are equal to: 2x+6y
