Q. What value of d is a solution to this equation?2d=12Choices:(A)d=6(B)d=7
Identify Operation: Identify the operation needed to solve for d. The equation is 2d=12, which means we need to isolate d by performing the inverse operation of multiplication, which is division.
Divide by 2: Divide both sides of the equation by 2 to solve for d. To isolate d, we divide both sides of the equation by 2, which gives us d=212.
Perform Division: Perform the division to find the value of d. Calculating the division from the previous step, we get d=6.
Check Solution: Check the solution by substituting the value of d back into the original equation.Substituting d=6 into the original equation gives us 2×6=12, which is true.
