解方程可以加悬赏分的我有114分哦
4.5+x=27.3
42=x-9
x+36=98
x-45=63
x÷11=11
x-7.2=14.3
1.8x=7.2
45+x=90
7x=42
y+24=96
305x=35
3.5+x=7

Answer 1

4.5+x=27.3 x=27.3-4.5=22.8
42=x-9 x=42+9=51
x+36=98 x=98-36=62
x-45=63 x=63+45=108
x÷11=11 =11*11=121
x-7.2=14.3 x=14.3+7.2=21.5
1.8x=7.2 =7.2/1.8=4
45+x=90 x=90-45=45
7x=42 x=42/7=6
y+24=96 x=96-42=54
305x=35 x=35/305=7/61
3.5+x=7 x=7-3.5=3.5
