解下列方程:1、4x+3(2x-3)=12-(x+4)?

解下列方程:1、4x+3(2x-3)=12-(x+4)?
解下列方程:1、4x+3(2x-3)=12-(x+4)?

解下列方程:1、4x+3(2x-3)=12-(x+4)?
4x + 3(2x - 3) = 12 - (x + 4)
4x + 6x - 9 = 12 - x - 4
10x - 9 = 8 - x
10x + x = 8 + 9
11x = 17
x = 17 ÷ 11
x = 17/11

4x + 3(2x - 3) = 12 - (x + 4)
4x + 6x - 9 = 12 - x - 4
10x - 9 = 8 - x
10x + x = 8 + 9
11x = 17
x = 17 ÷ 11
x = 17/11

4x+6x-9=12-x-4
11x=17
x=1.545
