How to solve for y
The solution of the given linearequation 5x+10=10y is .
Two algebraic expressions separated by an equal symbol in between them and with the same value of the expression are called equations.
Example = 2x +4 = 12
here, 4 and 12 are constants and x is variable.
The value of y can be calculated as:
5x+10=10y
Since, the equation is divisible by 5,
So, the equation becomes,
x+2=2y
Divide both sides by 2, to get the value of y
Thus, the value of y in the given equation 5x+10=10y is .
