Exercise 38 Page 160

Can the equation be written in standard form?

Linear? Yes.
Equation: 7n-6m=4

Practice makes perfect

To determine if the given equation is a linear equation, let's first see if we can rewrite it in standard form. Ax+ By= CIn this case, A, B, and C are constants and A and B cannot both be zero. In our case we have n and m, instead of x and y, respectively.

7n-8m=4-2m

LHS+2m=RHS+2m

7n-8m+2m=4

Add terms

7n-6m=4

This is the standard form of the given equation. Below we have highlighted how it corresponds to the general standard form. 7n-6m=4 ⇔ 7n+( -6)m= 4 When written this way, we can see that A= 7, B= -6, and C= 4. Since this equation can be written in standard form, it is linear.
