Question

(x + 3) :5=63:45. nilai x adalah .....
( pake cara nya ya ) thanks

Answer 1

(x+3)/5 = 63 : 45    (kali 5)
x + 3 = 63/9
x + 3 = 7
x = 7-3
x = 4

Answer 2

(x + 3) : 5 = 63 : 45

(x + 3) = 63
   5        45

kalikan silang

45x + (3 * 45) = (63 * 5)
45x + 135 = 315
45x = 315 - 135
45x = 180
x = 180 / 45
x = 4
