8/3x-50-10/5x+40=10怎么解
展开全部
解:解方程,此方程的解为x = 30
(8/3)x - 50 - (10/5)x + 40 = 10
(8/3)x - (10/5)x - 50 + 40 = 10
(40/15)x - (30/15)x - 10 = 10
(10/15)x = 10 + 10
(2/3)x = 20
x = 20 ÷ 2/3
x = 20 × 3/2
x = 10 × 3
∴x = 30
答:此方程的解为x = 30
(8/3)x - 50 - (10/5)x + 40 = 10
(8/3)x - (10/5)x - 50 + 40 = 10
(40/15)x - (30/15)x - 10 = 10
(10/15)x = 10 + 10
(2/3)x = 20
x = 20 ÷ 2/3
x = 20 × 3/2
x = 10 × 3
∴x = 30
答:此方程的解为x = 30
