Question

2x+4(x-1)=5x
6-3(1-x)+2(x-5)=3
3(2x+1)-5(x+2)=3x-4
2x+4x(1-x)=2+2(2x+5)
5x-4(2x+3)=3-2(4-5x)
4x+2(3x-1)=1+3(x-1)
7(x+1)=3(x-2)-4(5-x)

Answer 1

2x+4(x-1)=5x
2x+4x-4=5x
6x-5x=4
x=4

6-3(1-x)+2(x-5)=3
6-3+3x+2x-10=3
5x=3+7
x=10/5
x=2

3(2x+1)-5(x+2)=3x-4
6x+3-5x-10=3x-4
x-3x=7-4
-2x=3
x=-3/2

2x+4x(1-x)=2+2(2x+5)
2x+4x-4x²=2+4x+10
-4x²+6x-4x=12
-4x²+2x=12
2x(1-2x)=12
2x=12     x=12/2=6     
1-2x=12     -2x=12-1      -x=11/2     x=11/2

5x-4(2x+3)=3-2(4-5x)
5x-8x-12=3-8+10x
-3x-10x=-5+12
-13x=7
x=-7/13

4x+2(3x-1)=1+3(x-1)
4x+6x-2=1+3x-3
10x-3x=-2+2
7x=0
x=0/7
x=0

7(x+1)=3(x-2)-4(5-x)
7x+7=3x-6-20+4x
7x-7x=-26-7
0x=-33
x=-33/0
x=0
