Yeah lol Im a math wiz when it came to algebra xD I wanted to know if you know it

texaschic101 · Answer

take the number before the parenthesis and multiply it by everything in the parenthesis.
2(4x - 5) would be 8x - 10 ( I multiplied 2 by 4x and then multiplied 2 by -5. That gets rid of the parenthesis.
Now lets do this problem..
2(4x - 5) + 2 = 10 - 4(6x - 45)
8x - 10 + 2 = 10 - 24x + 180
8x - 8 = -24x + 190
8x + 24x = 190 + 8
32x = 198
x = 198/32 
x = 6.1875

or x = 6 6/32 which reduces to 6 3/16
