Answer:
<u>x= 12 </u>
Step-by-step explanation:
work backwards to find x. you start with 40, then subtract 16. now you have 2x= 24. now you have to figure out what multiplied by 2 is 24. 24 divided by 2 is 12, there is the answer. x=12. Always check your work, solve it normally replacing x with 12.
<em>2 x 12 + 16 =40</em>
<em>24 + 16 = 40</em>
<em>40.</em>
Answer:x=12
Step-by-step explanation:subtract 16 from both sides (16-16=0) (40-16=24)
2x=24 divide 2 to both sides (2/2=0) (24/2=12) hope i explained it correctly.
you always need to get x by itself so whatever is in from of x divide that by what ever is behind the equal(=) sign.
