Question

write a two-step equation that involves multiplication and subtraction, includes a negative coefficient, and has a solution of x=7

Answer 1

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:

$-3x-7=-28$

Answer 2

-60x+20 = -400
x equals 7
