Question

решите восьмое пожалуйста.

Answer 1

2х-43 - 3х-94 = х+ 193
8х-16-9х+2712 = х+193
-х+1112 = х+193
12*(х- 193) = -х+11
12х+ 2283 +х = 11
13х = 11/1 - 2283
13х = -1953
13х = -65
х = -5

Answer 2

$frac{2(x-2)}3-frac{3(x-3)}4=x+6frac13\frac{2x-4}3-frac{3x-9}4=x+frac{19}3\frac{4(2x-4)-3(3x-9)}{12}=frac{3x+19}3\frac{8x-16-9x+27}{12}=frac{3x+19}3\frac{11-x}{12}=frac{3x+19}3\3(11-x)=12(3x+19)\11-x=4(3x+19)\11-x=12x+76\13x=-65\x=-5$
