If (Y x 15+20=245), what does Y equal?
Y x 15+20=245
Y + 35 = 245
Y = 210
I changed signs when I shouldn't have.
15Y + 20 = 245
15Y = 245-20
15y = 225
Y = 15
To find the value of Y, we can solve the equation step by step.
The equation is:
Y x 15 + 20 = 245
To isolate Y, we need to get rid of the 20 first. We can do this by subtracting 20 from both sides of the equation.
Y x 15 + 20 - 20 = 245 - 20
Y x 15 = 225
Now, we have Y multiplied by 15. To isolate Y further, we can divide both sides of the equation by 15.
(Y x 15) / 15 = 225 / 15
Y = 15
Therefore, Y is equal to 15.
