You can put this solution on YOUR website!
4+3x = 4(2x-5)?
4+3x=8x-20
3x-8x-20-4
-5x=-24
x=-24/-5
x=24/5 or 4.8 ans.
-----------------------
8x-7+2x = 6+5x+2?
6x-7=5x+8
6x-5x=8+7
x=15 ans.
-----------------------
10(x-1) = 2(2x-5)?
10x-10=4x-10
10x-4x=4x-10
-4x-4x=-10-10
-8x=-20
x=-20/-8
x=5/2 or 2.5 ans.
-----------------------------
3x+7x = 16+4x?
10x-4x=16
6x=16
x=16/6
x=8/3 or 2 2/3 or 2.6667 ans.
