Question

$\frac{15-x}{6} - \frac{2x+16}{5} =1$

$\frac{5}{12} + \frac{x}{6} = \frac{x}{4} + \frac{x}{3}$

$\frac{x-1}{5} + \frac{x-2}{3} = 2- \frac{x-2}{15}$

5 -  x√5 = 3 - x√3
(x-1) * √2 = 2x -1

Answer 1

5(15-x)-6(2x+16)=30
75-5x-12x-96=30
-17x=51
x=-51/17=-3
5+2x=3x+4x
5=5x
x=1
3(x-1)+5(x-2)=30-x+2
3x-3+5x-10=32-x
9x=45
x=45/9=5
5-x√5=3-x√3
5-3=x√5-x√3
2=x(√5-√3)
x=2/√5-√3

(x-1)√2=2x-1
x√2-√2=2x-1
x√2-2x=√2-1
x(√2-2)=√2-1
x=√2-1/√2-2

Answer 2

a) 5(15-x)-6(2x+16)=30
75-5x-12x-96=30
-17x=51
x=-3
b)5+2x=3x+4x
5=5x
x=1
c)3(x-1)+5(x-2)=30-x+2
3x-3+5x-10=32-x
9x=45
x=5
d) 5-3=-x√3+x√5
2=x(√5-√3)
x=2/(√5-√3)
x=2(√5+√3)/2
x=√5+√3

e)x√2-√2=2x-1
x(√2-2)=-1+√2
x=(√2-1)/√2-2
x=(√2-1)(√2+2)/-2
x=2+√2-2/-2
x=-√2/2
