Then we divide through by 2, getting

x=− 3

For Prob. 2 (Table B-2). The standard-form equation we got was

17 x+ 6 = 0

We subtract 6 from each side, getting

17 x=− 6

Then we divide through by 17, getting

x=−6/17

For Prob. 3 (Table B-3). The standard-form equation we got was

43 x+ 49 = 0

We subtract 49 from each side, getting

43 x=− 49

Then we divide through by 43, getting

x=−49/43

For Prob. 4. The standard-form equation we got was

x− 24 = 0

We add 24 to each side, getting

x= 24

In this case, we need not multiply or divide through by anything, because x is already
by itself on the left side of the equation.

6. If we call the unknown number x, then we have the following equation to solve:

(2x+ 8)/4 =− 1
