x + x x 48 = 6860 : 35
x x ( 1 + 48 ) = 196
x x 49 = 196
x = 196 : 49
x = 4. Vậy x = 4
x+x×48=6860:35
x×1+x×48=196
x×(1+48)=196
x×49=196
x=196:49
x=4
x + x × 48 = 6860 : 35
x × 1 + x × 48 = 6860 : 35
x × (1+48) = 196
x × 49 = 196
x = 196 : 49
x = 4
X + X x 48 = 6860 : 35
X x 1 + X x 48 = 196
X x ( 1 + 48 ) = 196
X x 49 = 196
X = 196 : 49
X = 4
^ - ^
x + x . 48 = 6860 :35
x .2 . 48 = 196
x . 2 = 196 : 48
x . 2 = 4
x = 4: 2
x = 2
Vay x = 2
X + X x 48 = 6860 : 35
X x 2 x 48 = 196
X x 2 = 196 : 48
X x 2 = 49/12
X = 49/12 : 2
X = 49/24
