Sagot :
[tex]4(1+3x)+4x= -18+5x[/tex]
First, you develop, so you get:
[tex]4+12x+4x = -18+5x[/tex]
Then, you put known numbers (numbers without x) apart, and unknown numbers (numbers with x) apart. And remember, moving from a side to another change the sign of the Number (Positive become negative, and negative become positive) so you get:
[tex]12x+4x-5x = -18-4[/tex]
Now, you do the calculations, you get:
[tex]11x = -22[/tex]
Then, you move 11 to the other side. And since it was in a multiplication equation, it become a division. So you get:
[tex]x = - \frac{22}{11} [/tex]
[tex]x = -2[/tex]
Hope this Helps! :D

4(1 + 3x) + 4x = -18 + 5x
4(1) + 4(3x) + 4x = -18 + 5x
4 + 12x + 4x = -18 + 5x
4 + 16x = -18 + 5x
- 5x - 5x
4 + 11x = -18
- 4 - 4
11x = -22
11 11
x = -2
4(1) + 4(3x) + 4x = -18 + 5x
4 + 12x + 4x = -18 + 5x
4 + 16x = -18 + 5x
- 5x - 5x
4 + 11x = -18
- 4 - 4
11x = -22
11 11
x = -2
