y = -2.5 is a equation. And solution to the equation is finding the value of the variable. If we see the equation y is already equal to -2.5 which is the solution to the equation.
If you mean 28 = 7+y then the solution of the equation is y = 21
It is a simultaneous equation and its solution is x = -1 and y = -5
-1
(0, 6.5) is one option.
The solution consists of the infinite number of points on the line which is defined by y + x = 6.
Possibly the solution to an equation
An equation where y = 81
x = 0 and y = 4
The equation is [ 5y = 35 ].The solution to the equation is [ y = 7 ].
If for example: 4y = 16 Then: y = 4
Yes it is. The solution is: y=4 .
The equation 6 + y = 12 is a simple equation in one variable. If you add 6 to both sides of the equals sign, you get y = 18, and that is the solution.
Subtracting the second equation from first: 3x - y = 25 3x + 4y = 5 0x - 5y = 20 5y = -20 y = -4 Plugging y = -4 into either equation gives us x = 7, So x = 7 and y = -4
If you mean 28 = 7+y then the solution of the equation is y = 21
No. -4 does not equal -2(1).
Another solution for x+y = 7 is y = -x+7
Yes, Y = 24-17 Y = 7
