If 7:x=175:22.5, then find the value of x

2.45x + 1.5 = 3.7x - 2.25 then x=_____

Is {x : x^(2) - 5x -6=0} ={2,3} ?

If [[2,3],[4,5]]=[[x,3],[2x,5]] , then x =

Solve: (2x+7)/(3x+5) = 15/17 .

it [[3.5, x7, x, 7x, 5.3]] = 0

Statemenr I: If (3x+2)/(5)=(4x-7)/(6) thenx =23(1)/(2) Statement II: If 5(2x-9)/(3)8=2x then x=69/5

Assertion (A) : (1)/(5)+(1)/(3.5^(3))+(1)/(5.5^(5))+(1)/(7.5^(7))+…(1)/(2)log((3)/(2)) Reason (R ) : If |x| lt 1 then log_(e )((1+x)/(1-x))=2(x+(x^(3))/(3)+(x^(5))/(5)+…)
