It is (-1, 3).
y=x+1 there for answer is 2
3x + 2 = 82
It's an inconsistent pair of equations, for which there is no solution.
If: x = 7 Then: y = (2*7)+3 = 17 And: 5x+y = (5*7)+17 = 52
x + y = 17 + 23 = 40
When 5x+3 = 17 then x = 2.8 Therefore when 8x-y = 3 then x = 2.8 and y = 19.4
x = 14
x = y = 0 ?
-17 + y,,must be equals to..-17y..
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
-17 + y,,must be equals to..-17y..

(1, 9)
y equals x plus 5 is the equation of a straight line in the x-y plane.
(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.
