5x-3.5+6.5=18
5x-3.5+6.5=18解方程 -
解:5x-3.5+6.5=18 5x=18+3.5-6.5 5x=15 x=3
解∶ 5x=18+3.5-6.5 5x=15 x= 15÷5 x=3
解:5x-3.5+6.5=18 5x=18+3.5-6.5 5x=15 x=3
解∶ 5x=18+3.5-6.5 5x=15 x= 15÷5 x=3
解:解方程, 此方程的解为x = 3 5x - 3.5 + 6.5 = 18 5x + (6.5 - 3.5) 18 5x + 3 = 18 5x = 18 - 3 5x = 15 x = 15 ÷ 5 x = 15 × 1/5 x = 15/5 x = (3×5)5 ∴x = 3 答:此方程的解为x = 3 希望你能满意。
5x=18-6.5+3.5 5x=11.5+3.5 5X=15 x=3
