What are the ordered pair to equation x plus 7y equals 33 and equation 3x-2y equals 7?

x = 5 and y = 4


What is the order pair for x plus 7y equals 33 and 3x - 2y equals 7?

The ordered pair is (5, 4).


X plus 7y equals 33 and 3x - 2y equals 7?

x + 7y = 33 (1) --> x = 33 - 7y (1a) 3x - 2y = 7 (2) To solve the simultaneous equations, starts by substituting the value for x found in (1a) into (2): 3(33 - 7y) - 2y = 7 99 - 21y - 2y = 7 -23y = -92 y = 4 Now substitute this value for y into (1a) and solve for x: x = 33 - 7(4) x = 33 - 28 x = 5 Therefore these equations have the solution x = 5, y = 4


What is X plus 7y equals 33 and 3x - 2y equals 7?

x + 7y = 33 multiply through by 3: 3x + 21y = 99 Subtract the second equation from the above equation: 23y = 92 So y = 4 Substituting this value of y in the first equation, x + 28 = 33 ie x = 5 The solution is (x,y) = (5,4)


What is the y intercept of x plus 7y equals 7?

x + 7y = 7 ⇒ 7y = -x + 7 ⇒ y = -x/7 + 1 ⇒ y intercept is 1.


Use elimination to solve the system x plus 7y equals 16 and 3x - 7y equals 4?

x+7y=16 ---------------------------1 3x- 7y=4 ---------------------------2 ------------------------------------------------------------------------------------------------------------------ 1+2 x+7y=16 3x-7y=4 4x=20 x=5 substitute x = 5 in x+7y=16 (5)+7y=16 7y=11 y=11/7


3x plus 7y equals 37 and x equals 3 then y equals?

4


If x equals 2 and y equals 5 then 9x plus 7y equals?

If x equals 4 and y equals 5 then 9 x plus 7y equals?

x=4 y=5 9x+7y=?? Replace: 9(4)+7(5)= 71


What is 3x plus 7y equals -16 -x-y equals 4?

y = -1 and x = -3


X plus 7y equals 12 3x - 5y equals 10?
