解方程练习题带答案(甲数是32.8,比乙数的四倍少3.6,求乙数(用方程))

解设;乙为x. 4x-3.6=32.8解;4x=32.8+3.6 4x=36.4 x=9.1 乙为9.1

设乙数为x数
32.8=4x-3.6
32.8+3.6=4x
36.4=4x
x=9.1

设乙数是x
32.8=4x-3.6
4x=32.8+3.6
4x=36.4
x=9.1
乙数是9.1

设乙为X
4X-3.6=32.8
4X=32.8+3.6
4X=36.4
X=36.4/4
X=9.1

设乙数为x
4x-3.6=32.8
4x=32.8+3.6
4X=36.4
X=36.4/4
X=9.1

乙数=x
4x-3.6=32.8
x=9.1

解设;乙为x. 4x- 3.6=32.8 解;4x=32.8+3.6 4x=36.4 x=9.1

设乙数是X
则 32.8=4x-3.6
4x=36.4
x=9.1

设乙数为x
由题意知 4x-3.6=32.8
4x=36.4
x=9.1
答:乙数是9.1
