70*x=126 \\ \\ (70)/(100) *x=126 \\ \\ (7)/(10)*x=126 \\ \\ x=126: (7)/(10) \\ \\ x=126* (10)/(7) \\ \\ x= (1260)/(7) \\\\ \boxed{x=180} \\\\\huge\text{The answer is x=180}

let the number be a ...

i.e ,70% of a =126 ..
=> 70/100 X a =126
=>7/10 a =126
=>7 a = 126 X 10
=>7 a= 1260
=>a = 1260/7
a = 180 ..

Hope it helps !!!
