3.5X+3.5×5=33.25 要过程

问题描述:

3.5X+3.5×5=33.25 要过程

3.5x+3.5*5=33.25
3.5x=33.25-3.5*5
3.5x=33.25-17.5=15.75
3.5x=15.75
x=15.75/3.5
=4.5

3.5X+17.5=33.25
3.5X=15.75
X=4.5

3.5(X+5)=33.25
X+5=33.25/3.5
X+5=9.5
X=4.5

3.5X+3.5×5=33.25
3.5(5+x)=33.25
5+x=9.5
x=4.5

3.5X+3.5×5=33.25 两边除3.5
x+5=9.5
x=9.5-5
x=4.5

3.5X+3.5×5=33.25
3.5(x+5)=33.25
x+5=33.25÷3.5
x=9.5-5
x=4.5

3.5(x+5)=33.25
x+5=9.5
x=4.5
