Question

Simplify the following (7m – 3y) – (2m + 6y)

Answer 1

Answer:

$5m-9y$

Step-by-step explanation:

$7m-3y-(2m+6y)$

Distribute the negative sign to 2m+6y.

$7m+-3y+-2m+-6y$

Combine the like terms.

$7m+-2m+-3y+-6y$

$5m-9y$

Step by step solution :

Step  1  :

           y4

Simplify   ——

           2  

Equation at the end of step  1  :

                 y4

 (((7 • (m-3)) • ——) • m(-6)) • y(-2)

                 2  

Step  2  :

Equation at the end of step  2  :

            y4

 ((7m(-3) • ——) • m(-6)) • y(-2)

            2  

Step  3  :

Equation at the end of step  3  :

  7y4

 (——— • m(-6)) • y(-2)

  2m3

Step  4  :

Dividing exponential expressions :

4.1    m(-6) divided by m3 = m((-6) - 3) = m(-9) = 1/m9

Equation at the end of step  4  :

 7y4

 ——— • y(-2)

 2m9

Step  5  :

Multiplying exponential expressions :

5.1    y4 multiplied by y(-2) = y(4 + (-2)) = y2

Final result :

 7y2
