Distribute 4 across parentheses: We are given the equation B=4(8−y).To find the value of y, we need to solve for y in this equation.First, we can distribute the 4 across the parentheses.So, B=4×8−4×y.
Perform multiplication: Now, we perform the multiplication.4×8=32 and 4×y=4y.So, the equation becomes B=32−4y.
Isolate y in equation: To solve for y, we need to isolate y on one side of the equation.We can start by subtracting 32 from both sides of the equation.This gives us B−32=−4y.
Divide by −4: Now, we divide both sides of the equation by −4 to solve for y.(B−32)/−4=y.
Express y in terms of B: We have now isolated y and expressed it in terms of B. So, the value of y in terms of B is y=−4B−32.
