Y equals -x plus 12x-y equals 5 solve by substitution?
17
What is the solution of the system -x plus y equals 4 and x plus y equals 2?
It is (-1, 3).
What describes how to translate the graph y equals x to obtain the graph of y equals x plus 1 plus 1?
y=x+1 there for answer is 2
For x plus y plus z equals 9 2x-y-z equals -6 and x plus y-z equals 1 what is the echelon matrix?
3x + 2 = 82
What is X plus y equals 120 x plus y equals 150?
It's an inconsistent pair of equations, for which there is no solution.
If x equals 7 and y equals 2x plus 3 what is 5x plus y?
If: x = 7 Then: y = (2*7)+3 = 17 And: 5x+y = (5*7)+17 = 52
If x and y are prime numbers and 3x plus 4y equals 143 then what is the value of x plus y?
x + y = 17 + 23 = 40
8x-y equals 4 5x plus 3 equals 17?
When 5x+3 = 17 then x = 2.8 Therefore when 8x-y = 3 then x = 2.8 and y = 19.4
If x plus 2 equals y and y equals 16 what is the value of x plus y?
x = 14
3x plus y equals 4 x plus y equals 0?
x = y = 0 ?
What does 3x equals -17 plus y?
-17 + y,,must be equals to..-17y..
X plus y plus z equals 9 and x plus 2y plus 3z equals 23 and x plus 5y-3Z equals -7 solve for x and y and z?
Can you help with this equation? Thanks. Solve for x and y and z for the following. x plus y plus z equals 9 x plus 2y plus 3z equals 23 x plus 5y plus -3z equals -7
Y equals -x plus 12x-y equals 5 solve by substitution?
17
What does y plus y equals?
-17 + y,,must be equals to..-17y..
X plus y equals 10 and y equals x plus 8?
(1, 9)
What is the answer to y equals x plus 5?
y equals x plus 5 is the equation of a straight line in the x-y plane.
Solve by the elimination method x plus 6y equals 19 -x plus 6y equals 17?
(A) x + 6y = 19 (B) -x + 6y = 17 (A)+(B): 12y = 36 so that y = 3 Substituting this value of y in (A), x + 18 = 19 so x = 1.
