展开全部
解:解方程, 此方程的解为x = 1/18
(3/7)x + 1/7 = 1/6
(3/7)x = 1/6 - 1/7
(3/7)x = (1×7)/(6×7)- (1×6)/(7×6)
(3/7)x = 7/42 - 6/42
(3/7)x = 1/42
x = 1/42 ÷ 3/7
x = 1/42 × 7/3
∴x = 1/18
答:此方程的解为x = 1/18
(3/7)x + 1/7 = 1/6
(3/7)x = 1/6 - 1/7
(3/7)x = (1×7)/(6×7)- (1×6)/(7×6)
(3/7)x = 7/42 - 6/42
(3/7)x = 1/42
x = 1/42 ÷ 3/7
x = 1/42 × 7/3
∴x = 1/18
答:此方程的解为x = 1/18
