Answer:
The next step should be ''add 7x''.
Step-by-step explanation:
Given : If the first step in the solution of the equation \(-8-7x=-5x-10\) is "add 10,"
To find : What should the next step be?
Solution :
Equation \(-8-7x=-5x-10\)
Step 1 - Add 10 both side,
\(-8-7x+10=-5x-10+10\)
\(-7x+2=-5x\)
Step 2 - Add 7x both side,
\(-7x+2+7x=-5x+7x\)
\(2=2x\)
Step 3 - Divide both side by 2,
\(\frac{2}{2}=\frac{2x}{2}\)
\(1=x\)
Therefore, The next step should be ''add 7x''.
