Question

1)$\frac{x-8}{x+2} = \frac{7}{6}$ 2)$\frac{4}{x-1.2} } = \frac{15}{x-10 }$

Answer 1

1)
7(x+2)=6(x-8)
7x+14=6x-48
7x-6x=-48-14
x=-62
===========
2)
15(x-1,2)=4(x-10)
15x-18=4x-40
15x-4x=-40+18
11x=-22
x=-22:11
x=-2
=================

Answer 2

$\frac{x-8}{x+2} = \frac{7}{6}$
6(х-8)=7(х+2)
6х-48=7х+14
6х-7х=14+48
- х=62
х= - 62

$\frac{4}{x-1.2} = \frac{15}{x-10}$
4(х-10)=15(х-1,2)
4х-40=15х-18
4х-15х= - 18+40
- 11х=22
х= - 22:11
х= - 2
