Question

解方程.1.2X=7.2 X+1.5=10 4(X+2.4)=24.8 5X-4*9=24 0.81/X=0.9 6+4？

Answer 1

1.2X=7.2
X=7.2/1.2
X=6
X+1.5=10
X=10-1.5
X=8.5
4(X+2.4)=24.8
X+2.4=24.8/4
X+2.4=6.2
X=6.2-2.4
X=3.8
5X-4×9=24
5X=24+36
5X=60
X=60/5
X=12
0.81/X=0.9
X=0.81/0.9
X=0.9
6+4X=10
4X=10-6
4X=4
X=4/4
X=1,9,解方程.1.2X=7.2 X+1.5=10 4(X+2.4)=24.8 5X-4*9=24 0.81/X=0.9 6+4X=10
