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.
- If we call the unknown number x, then we have the following equation to solve:
(2x+ 8)/4 =− 1
