There is no equation in the question!
xy + x + y + 1 is an expression, not an equation. An expression cannot be solved.
(4 ± i2) where i2 = -1
what is the value of "N"? we can solve this equation when we know the value of N, once we know the value of N we just add 1 to it,
-1
To solve the equation you need to know at least a value for x or y. For example if x = 2 then the solution will show that y = 1.
Is this the right equation: 0.71 = 1 / (1 + g)4 ? Or is THIS the right equation: 0.71 = 1 / (1 + g4) ? There's a difference.
Y=0.5 and X=1
The solution to the equation 2x plus 2 is 2(x + 1).
xy + x + y + 1 is an expression, not an equation. An expression cannot be solved.
The answer to the equation 80 times 3 Y plus 2 Y plus 4 plus 1 equals -15. This is considered to be a math problem.
If: 2a+13 = 5a+1 Then: a = 4
(4 ± i2) where i2 = -1
n = 28
(2a + 1)(4a2 - 2a + 1)
If you mean: 80 = 3y+2y+4+1 then 80 =5y+5 and so y = 15
You don't "solve" an expression. You can solve an equation; an expression can be simplified or otherwise manipulated, and if you know the value of "x" (in this case), you can evaluate its value.
what is the value of "N"? we can solve this equation when we know the value of N, once we know the value of N we just add 1 to it,
