Question

Solve for x.

7x = 78

Answer 1

x = 78 / 7

Answer 2

You want to isolate x on one side of the equation. Since we have 7 times x on the left side, we want to divide both sides by 7. On the left side this will leave you with x by itself.

Answer 3

7x = 78
x=78/7
x=11.1428

Answer 4

so x=11 1/7?

Answer 5

no just x = 78 / 7

Answer 6

Answer 7

Answer 11

\[\frac{78}{7} = \frac{77 + 1}{7} = \frac{77}{7} + \frac{1}{7} = 11 + \frac{1}{7} = 11\frac{1}{7}\]
