Question 183876
<font face="Times New Roman" size="+2">


*[tex \LARGE \text{          }\math 3w-4=w+8]


Add -<i>w</i> to both sides:


*[tex \LARGE \text{          }\math 3w + (-w) - 4 = w + (-w) + 8]


*[tex \LARGE \text{          }\math 2w - 4 = 8]


Add 4 to both sides:


*[tex \LARGE \text{          }\math 2w - 4 + 4 = 8 + 4]


*[tex \LARGE \text{          }\math 2w = 12]


Multiply both sides by *[tex \Large \frac{1}{2} ]


*[tex \LARGE \text{          }\math \left(\frac{1}{2}\right) 2w = \left(\frac{1}{2}\right)12]


*[tex \LARGE \text{          }\math w = 6] 


Check the answer:


*[tex \LARGE \text{          }\math 3(6) - 4 =^? (6)+8]


Is the answer correct?
