Salut

a)√3(x-2)+2√3(x+1)=6√3

√3x-2√3+2√3x+2√3=6√3

√3x+2√3x=6√3

3√3x=6√3

x=2.

b)2√3(x+2)+4√6=3√3(2x+2√2)-2√3

2√3x+4√3+4√6=6√3x+6√6-2√3

-4√3x=2√6-6√3

x=- 2(√6-3√3)/4√3

x=- √6-3√3/2√3

x=9-√18/6

x=9-3√2/6

x=3(3-√2)/6

x=3-√2/2.

c)2x(√3+√2)-√2(3+2x)=√3(x+√2)

2√3x-3√2=√3x+√6

2√3x-√3x=√6+3√2

√3x=√6+3√2

x=√6+3√2/√3

x=(√6+3√2)√3/√3

x=√18+3√6/√3

x=3√2+3√6/3

x=3(√2+√6)/3

x=√2+√3.
