4x=y
4(7)=28 x=7 y=28
4(-5)=-20 x=-5 y=-20
4(-3)=-12 x=-3 y=-12
yes
but what is the question?
We have to plug in x as a number. 4x=y is the equation we use to do that
Oh, ok, you did it fine.
4x=y
4(3)=12 x=3 y=12
4(-7)=-28 x=-7 y=-28
sure, good
The given equation is 4x = y. Let's calculate the value of y for given values of x.
For x = 7:
Substituting x = 7 into the equation, we have 4(7) = y.
Evaluating the expression on the left side of the equation gives us 28 = y.
Therefore, when x = 7, y = 28.
For x = -5:
Substituting x = -5 into the equation, we have 4(-5) = y.
Evaluating the expression on the left side of the equation gives us -20 = y.
Therefore, when x = -5, y = -20.
For x = -3:
Substituting x = -3 into the equation, we have 4(-3) = y.
Evaluating the expression on the left side of the equation gives us -12 = y.
Therefore, when x = -3, y = -12.
To find the value of y for a given value of x in the equation 4x = y, you can simply substitute the value of x into the equation and solve for y.
