Question

解方程：X+8-15=34 2(X+5)=13.6 X-0.36X=16

是X+8-15=34 、2（X+5）=13.6、X-0.36X=16

Answer 1

x=41,x=1.8,x=25

Answer 2

X+8-15=34
X=34-8+15
X=41

2(X+5)=13.6
X+5=13.6÷2
X+5=6.8
X=6.8-5
X=1.8

X-0.36X=16
(1-0.36)X=16
0.64X=16
X=16÷0.64
X=25

Answer 3

X+8-15=34 x=41
2(X+5)=13.6 x=1.8
X-0.36X=16 x=25

Answer 4

X+8-15=34
X=34+15-8
X=41

2（X+5）=13.6
X+5=13.6/2
X+5=6.8
X=6.8-5=1.8

X-0.36X=16
(1-0.36)X=16
0.64X=16
X=16/0.64
X=25
