解方程17.2十4x=45.2
解方程17.2十4x=45.2 -
解方程17.2十4x=45.2 解:原方程即:4x=45.2-17.2 4x=28 x=28÷4 x=7 把x=7代入原方程检验,17.2+4x7 =17.2+28 =45.2
4x=45.2-17.2 x=58÷4 x=14.5
解方程17.2十4x=45.2 解:原方程即:4x=45.2-17.2 4x=28 x=28÷4 x=7 把x=7代入原方程检验,17.2+4x7 =17.2+28 =45.2
4x=45.2-17.2 x=58÷4 x=14.5
1.8x+9.2=45.2 1.8x=45.2-9.2 1.8x=36 x=36÷1.8 x=20
3.84x=45.2 x=45.2÷3.84 ∴x=565/48
45.2一x的4倍,差是17.2 -
45.2一x的4倍,差是17.2,也即:45.2-4x=17.2 -4x=17.2-45.2 -4x=-28 x=7 希望帮到你望采纳 谢谢加油!
3.2x=45.2+1.2 3.2x=46.4 x=46.4/3.2=14.5
45.2减x的四倍差是17.2怎么解? -
45.2-4x=17.2 4x=45.2-17.2 4x=28 x=7
回答:2x=45.2-18 2x=27.2 x=13.6
3.2x-1.2=45.2解方程 -
3.2x-1.2=45.2 3.2x=45.2+1.2 3.2x=46.4 x=46.4÷3.2 x=14.5
解:解方程,此方程的解为x = 100 0.5x - 4.8 = 45.2 0.5x = 45.2 + 4.8 (5/10)x = 50 (1/2)x = 50 x = 50 ÷ 1/2 x = 50 × 2 ∴x = 100 答:此方程的解为x = 100
