Answer 1

b)1+√3x=x+2

√3x-x=2-1

x(√3-1)=1

x=1/(√3-1) =(√3+1)/(3-1) =(√3+1)/2

 

 

d)2x+3+x√3=4

2x+x√3=4-3

x(2+√3)=1

x=1/(2+√3)=(2-√3)/(4-3)= (2-√3)

 

f)√5(x-√5)=10-x

√5x-5=10-x

√5x+x=10+5

x(√5+1)=15

x=15/(√5+1)=(√5-1)/(5-1) =(√5-1)/4

 

h)(2x-3)/x√7=1/2

x√7 =2(2x-3)

x√7=4x-6

x√7-4x=-6

x(√7-4)=-6

x=-6/(√7-4)=6(√7+4)/(7-16) =(6√7+24)/-9
