Answer:
Hence, the equation is:
\(-3x-7=-28\)
and the solution is:
\(3x=28-7\\\\3x=21\\\\x=7\)
Step-by-step explanation:
A two step equation is a equation that takes just two steps to solve.
Now we have to formulate a two-step equation that involves multiplication and subtraction, includes a negative coefficient, and has a solution of x=7.
negative coefficient means that the coefficient of the variable term must be negative.
so, we take a equation as:
\(-3x-7=-28\)
Clearly the coefficient of variable term is: -3 which is negative.
Now we solve the equation as:
\(3x=28-7\\\\3x=21\\\\x=7\)
Hence, the equation is:
\(-3x-7=-28\)
