Question

(1/2)2(x+0.5)-3(x-0.4)=5.6,3-2(2x+1)=2(x-3),15-(7-5x)=2x+(5-3x),3(x+1)-(

Answer 1

2(x+0.5)-3(x-0.4)=5.6,
2x+1-3x+1.2=5.6
x=2.2-5.6
x=-3.4

3-2(2x+1)=2(x-3),
3-4x-2=2x-6
6x=7
x=7/6

15-(7-5x)=2x+(5-3x)
15-7+5x=2x+5-3x
6x=-3
x=-1/2

Answer 2

2(x+0.5)-3(x-0.4)=5.6
2x+1-3x+1.2=5.6
-x+2.2=5.6
-x=5.6-2.2
-x=3.4
x=-3.4

3-2(2x+1)=2(x-3),
3-4x-2=2x-6
1-4x=2x-6
2x+4x=1+6
7x=6
x=6/7

15-(7-5x)=2x+(5-3x),
15-7+5x=2x+5-3x
8+5x=5-x
6x=-3
x=-1/2

Answer 3

2(x+0.5)-3(x-0.4)=5.6
x=-3.4
3-2(2x+1)=2(x-3)
x=7/6
15-(7-5x)=2x+(5-3x)
x=-1/2
3(x+1)-(3x-2)=4(x-5)
x=25/4
3(y+2)-2=2y-(y+5)
y=-9/2
3[y-2(y-1)]=4y
y=6/7
