Answer:
D. Divide both sides of the equation by 7.
Step-by-step explanation:
Given expression:
[tex]7d=49[/tex]
To determine the step used to isolate the variable in the above equation.
Step:
In order to isolate [tex]d[/tex] in the above equation we would divide both sides of the equation by [tex]7[/tex]. By doing this the [tex]7[/tex] on the left side would cancel out isolating [tex]d[/tex].
The step is done as follows:
[tex]7d=49[/tex]
Dividing both sides of te equation by 7.
[tex]\frac{7d}{7}=\frac{49}{7}[/tex]
∴ [tex]d=7[/tex]
