Step-by-step explanation:
<u>Step 1: Define</u>
0.4(12 - 3x) = 0.3(12x - 16)
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute: 4.8 - 1.2x = 3.6x - 4.8
- Add 1.2x on both sides: 4.8 = 4.8x - 4.8
- Add 4.8 on both sides: 9.6 = 4.8x
- Divide 4.8 on both sides: 2 = x
- Rewrite: x = 2
Answer:
The solution for the given algebraic equation is 
Step-by-step explanation:
Given algebraic equation as :
( x - 8 ) + 1 = 2 ( 18 x - 1 )
Now solving the equation while opening the brackets
So,
× x -
× 8 + 1 = 2 × 18 x - 2
Or,
-
+ 1 = 36 x - 2
or,
- 4 + 1 = 36 x - 2
or,
- 3 = 36 x - 2
or,
- 36 x = - 2 + 3
Or,
- 36 x = 1
or,
= 1
or,
= 1
∴ 71 x = - 2
I.e x = 
Hence The solution for the given algebraic equation is
