Question

420+65.4=(x+175):5+30

Answer 1

420+65.4=(x+175):5+30

=> 420 + 260 = ( x + 175 ) : 5 + 30

=> 680 = ( x + 175 ) : 5 + 30 <=> ( x + 175 ) : 5 + 30 = 680

=> ( x + 175 ) : 5 = 650

=> x + 175 = 3250

=> x = 3075

 

Answer 2

420+65.4=(X+175):5+30

=>420+260=(X+175):5+30

=>680=(X+175):5+30

=>680-30=(X+175):5

=>650=(X+175):5

=>650.5=X+175

=>3250=X+175

=>X=3250-175

=>X=3075
