What else can I help you with?
2x plus 3y equals 17and3x plus 4y equals 24then5x plus 7y equals?
2x + 3y = 17 3x + 4y = 24 (2x + 3x) + (3y + 4y) = (17 + 24) 5x + 7y = 41
What is the slope of 3x plus 3y equals 12?
The slope is -1. 3x+3y=12 Subtract 3x 3y=-3x+12 Divide by 3 y=-x+4
Is 3x plus 5y equals 12 perpendicular to 5x plus 3y equals 18?
No.
Solve for x 2x plus 2y equals 8 3x plus 3y equals 6?
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!
Find the solution 3x-3y equals 12 and 3x plus y equals 8?

2x plus 3y equals 17and3x plus 4y equals 24then5x plus 7y equals?
2x + 3y = 17 3x + 4y = 24 (2x + 3x) + (3y + 4y) = (17 + 24) 5x + 7y = 41
4x-3y equals 11 3x-5y equals -11?
no, 4x-3y=11x 3x-5y doesn't equal -11
What is the slope of 3x plus 3y equals 12?
The slope is -1. 3x+3y=12 Subtract 3x 3y=-3x+12 Divide by 3 y=-x+4

What is x and y in 3x plus 3y equals 17.7 and 2x plus 3y equals 15.55?
x = 2.15 and y = 3.75
2x plus 3y equals 13 3x minus y equals 3 x equals?
2x+3y=13 3x-y=3 x=2
Find the solution 3x-3y equals 12 and 3x plus y equals 8?

-2x plus 3y equals -7 3x plus y equals 16?
-2x + 3y = -7 3x + y = 16 simultaneous equations. Elimination a letter. Arbitrarily select 'y' Hence multiply the bottom eq'n by ' -3' Hence -2x + 3y = -7 -9x - 3y = -48 Add the eq'ns/ -11x = =55 x = -55/-11 = 5 When x = 5 , substitute into either eq'n for 'y' -2(5) + 3y = -7 -10 + 3y = -7 3y = 3 y = 1 Hence answer in ( x,y) fpr, is ( 5,1).
