7x+1= 4x+10 Isolate binomials (anything with x)
7x-4x +1=10 Move the monomial (+1)
7x-4x= 10-1 Simplify
3x=9 Divide by 3
$\frac{3x}{3} = \frac{9}{3}$ Simplify
x=3

Answer: x=5

Step-by-step explanation:

$\frac{2}{14} =\frac{x}{35}$

$\frac{x}{35}=\frac{2}{14}$

simplify

$\frac{x}{35}=\frac{1}{7}$

$\frac{35x}{35}=\frac{1\cdot \:35}{7}$

$\frac{1}{7} \cdot 35=5$
