Answer:
1. [tex]x=4[/tex]
2.[tex]x=\frac{57}{7}[/tex]
3.[tex]x=\frac{27.7}{11}[/tex]
Explanation:
Given the following questions:
[tex]12=3x[/tex]
[tex]7x=57[/tex]
[tex]11x=27.7[/tex]
In order to find the answers to these questions, we have to recognize that in order to isolate the variable we need to divide on both sides.
Question one:
[tex]12=3x[/tex]
[tex]\frac{3x}{3} =\div3[/tex]
[tex]12\div3=4[/tex]
[tex]x=4[/tex]
Question two:
[tex]7x=57[/tex]
[tex]\frac{7x}{7} =\div7[/tex]
[tex]57\div7=8.14285714=\frac{57}{7}[/tex]
[tex]x=\frac{57}{7}[/tex]
Question three:
[tex]11x=27.7[/tex]
[tex]\frac{11x}{11} \div11[/tex]
[tex]27.7\div11=2.51818182=\frac{27.7}{11}[/tex]
[tex]x=\frac{27.7}{11}[/tex]
Hope this helps.
