x与18.4的和乘0.24的结果是12,求x.列式计算.
x与18.4的和乘0.24的结果是12,求x.列式计算.
(x+18.4)*0.24=12
x+18.4=12/0.24
x+18.4=50
x=50-18.4
x=31.6
(x+18.4)×0.24=12
x+18.4=12÷0.24
x+18.4=50
x=50-18.4
x=31.6
(x+18.4)*0.24=12
(x+18.4)*0.24/0.24=12/0.24
x+18.4=50
x+18.4-18.4=50-18.4
x=31.6
据题设→x+18.4=50→x=50-18.4=31.6。
12/0.24-18.4=31.6
x=31.6
