Question 1
12 - 8x = 7x - 4 - 4x
12 - 8x = 3x - 4
16 = 11x
x = 16 / 11
Question 2
5 - 8x + 1 = 6 - 6x + 2
6 - 8x = 8 - 6x
- 2 = 2x
x = - 1

A)
4(3-2x)=7x-4(1+x)
12-8x=7x-4-4x
12-8x=3x-4
12+4=3x+8x
16=11x
x=16/11
B)
5-(8x-1) = 6(1-x)+2
5-8x+1=6-6x+2
6-8x=8-6x
6-8=-6x+8x
-2=2x
x=-2/2
x=-1

you will be able to desire to flow each and every of the x's to a minimum of one area of the equation and all the numbers to the numerous. You try this by ability of using appearing the numerous operation. Step a million: upload 7 to the two aspects 3x-7=5x+13 -----> 3x=5x+20 Step 2: Subtract 5x from the two aspects 3x=5x+20 ----> -2x=20 Step 3: Divide 20 by ability of using -2 to remedy for x -2x=20 ----> x= -10 hopefully those steps make adventure! :) stable fulfillment at some thing of the questions!

4(3 - 2x) = 7x-4(1+x)
12-8x=7x-4-4x
12-8x=3x-4
-8x-3x=-4-12
-11x=-16
x=-16/-11
x=16/11
5-(8x-1) = 6(1-x)+2
5-8x-1=6-6x+2
4-8x=8-6x
-8x-6x=8-4
-14x=4
x=4/-14
x= wait... no... what...
