x=4/2
x=2
Answer:
- A. X=-12
- B. X=102
- C. X=44
- D. X=15
Step-by-step explanation:
Isolate the term of x from one side of the equation.
<h3><u>Part A. x-9=-21</u></h3>
<u>First, add by 9 from both sides.</u>
x-9+9=-21+9
<u>Solve.</u>
-21+9=-12
<u>X=-12</u>
<h3><u>Part B. 10+x=112</u></h3>
<u>Switch sides.</u>
x+10=112
<u>Subtract by 10 from both sides.</u>
x+10-10=112-10
<u>Solve.</u>
112-10=102
<u>X=102</u>
<h3><u>Part C. 14=x-30</u></h3>
<u>Switch sides.</u>
x-30=14
<u>Add by 30 from both sides.</u>
x-30+30=14+30
<u>Solve.</u>
<u>x=44</u>
<h3><u>Part D. 12-x=3</u></h3>
<u>Switch sides.</u>
x-12=3
<u>Add by 12 from both sides.</u>
x-12+12=3+12
<u>Solve.</u>
<u />
<u>Add the numbers from left to right.</u>
3+12=15
<u>x=15</u>
- <u>Therefore, the correct answer is part A: x=-12, part B: x=102, part C: x=44, and part D: x=15.</u>
