7(x + 10) = 100
First, divide both sides by 7. / Your problem should look like: [tex]x + 10 = \frac{100}{7} [/tex]
Second, subtract the 10 from both sides. / Your problem should look like: [tex]x = \frac{100}{7} - 10[/tex]
Third, simplify. / Your problem should look like: [tex]x = \frac{30}{7} [/tex]
Answer as fraction: [tex]x = \frac{30}{7} [/tex]
Answer as decimal: 4.2857
