13m-22=9m-6
13m-9m=22-6  <-- integer signs change when it goes to the other side of the  equal to sign
4m=16
m=16/4

Simplify the expression. State any excluded values.<br><br> x^ 2 - 36/42x - 7x^ 2
REY [17]

Consider the expression x^2-\dfrac{36}{42}x-7x^2.

This expression contains two terms with x^2, group them:

x^2-7x^2=x^2(1-7)=-6x^2.

Now simplify term \dfrac{36}{42}x=\dfrac{6}{7}x.

Now x^2-\dfrac{36}{42}x-7x^2=-6x^2-\dfrac{6}{7}x=6\left(-x^2-\dfrac{1}{7}x\right)=-6x\left(x-\dfrac{1}{7}\right).

This expression is defined for all x.
