Equation:
Equation x^2-2x=0
Equation x^2-3x-10=0
Equation (x-119)/(x+7)=-5
Equation x/4+13=x+1
Express {x} in terms of y where:
15*x-5*y=-5
18*x+20*y=-2
15*x+7*y=2
12*x-20*y=10
Identical expressions
two *(a/x+arctg(x/ two))= zero
2 multiply by (a divide by x plus arctg(x divide by 2)) equally 0
two multiply by (a divide by x plus arctg(x divide by two)) equally zero
2(a/x+arctg(x/2))=0
2a/x+arctgx/2=0
2*(a/x+arctg(x/2))=O
