✔ 最佳答案
-4x - 4 - 7x - 6 = 67x+4x = -4-6-6
collect like terms
11x = -16
divide both sides by 11
x = -16/11;

-4x -4 -7x -6 = 6
-4x -7x = 6 +4 +6
-11x = 16
x = -16/11
or
x = -1.45 (corr. to 3 sig. fig.)
-4x -7x = 6 +4 +6
-11x = 16
x = -16/11
or
x = -1.45 (corr. to 3 sig. fig.)

First leave the x's on the left hand side of the equation and move everything else to the right hand side of the equation:
-4x - 7x = 6 + 4 + 6
-11x = 16
Then solve for x:
x = 16/-11 = (-1.454545)
-4x - 7x = 6 + 4 + 6
-11x = 16
Then solve for x:
x = 16/-11 = (-1.454545)

Collect like terms....
-11x-10=6
Add ten to both sides....
-11x=16
Divide by -11
x= -16/11
x=1.4545454......
-11x-10=6
Add ten to both sides....
-11x=16
Divide by -11
x= -16/11
x=1.4545454......

-11x=16
x=-16/11=-1.454545....=-1.(45)
x=-16/11=-1.454545....=-1.(45)

combine terms
-11 x - 10 = 6
add 10 to both sides
11 x = 16
x = 16/11
-11 x - 10 = 6
add 10 to both sides
11 x = 16
x = 16/11

-11x -10 = 6
-11x = -4
x = .3636363
-11x = -4
x = .3636363
