Question

Solve for x (1.) 5/10x-9=8 (2.) 3/4x-3=1+5/12x

Answer 1

Answer:

1). $x=\frac{5}{170}$

2). $x=\frac{1}{12}$

Step-by-step explanation:

(1.)  $\frac{5}{10x}-9=8$

adding 9 on both sides we get

$\frac{5}{10x}=9+8$

$\frac{5}{10x}=17$

$5=17 \times 10x$

$x=\frac{5}{170}$

(2.)  $\frac{3}{4x}-3=1+\frac{5}{12x}$

$\frac{3}{4x}-\frac{5}{12x}=1+3$

$\frac{9-5}{12x}=4$

$\frac{4}{12x}=4$

$12x=1$

$x=\frac{1}{12}$
