Question

these are two math questions please help me​

Answer 1

Answer:

2 question answer 9/4

Step-by-step explanation:

36x - 35 - 35x + 40 = 48 - 12x + 1

x - 5 = 48 - 12x + 1

x + 12x = 48 + 5 + 1

x + 12x = 54

x + x = 54/2

2x = 9/2

× = 9/2×2

x = 9/4

Answer 2

Question:

To solve the following equations.

$\sf Part \ 1: \ \dfrac{2x - 13}{5} - \dfrac{x -3}{11} = \dfrac{x - 9}{5} +1\\ \\ \\\sf Part \ 2: \ 6(6x - 5) - 5(7x - 8) = 12(4 - x) + 1$

$\rule{250}{1}$

Solution:

$\sf Part \ 1: \ \dfrac{2x - 13}{5} - \dfrac{x -3}{11} = \dfrac{x - 9}{5} +1$

$\Longrightarrow \sf \ \dfrac{2x - 13}{5} - \dfrac{x -3}{11} = \dfrac{x - 9}{5} +1\\ \\ \\\Longrightarrow \sf \ \dfrac{2x - 13}{5} - \dfrac{x - 9}{5} = \dfrac{x -3}{11}+1\\ \\ \\\Longrightarrow \sf \ \dfrac{2x - 13 - (x - 9)}{5} = \dfrac{x -3 + 11}{11}\\ \\ \\\Longrightarrow \sf \ \dfrac{2x - 13 - x + 9}{5} = \dfrac{x + 8}{11}\\ \\ \\\Longrightarrow \sf \ \dfrac{x - 4}{5} = \dfrac{x + 8}{11}\\ \\ \\\Longrightarrow \sf \ 11(x - 4) = 5(x + 8)\\ \\ \\\Longrightarrow \sf \ 11x - 44 = 5x + 40$

$\Longrightarrow \sf \ 11x - 5x = 40 + 44\\ \\ \\\Longrightarrow \sf \ 6x = 84\\ \\ \\\Longrightarrow \sf \ x = \dfrac{84}{6} \\ \\ \\\Longrightarrow \sf \ x = 14$

Answer: x = 14

$\sf Part \ 2: \ 6(6x - 5) - 5(7x - 8) = 12(4 - x) + 1$

$\Longrightarrow \sf 6(6x - 5) - 5(7x - 8) = 12(4 - x) + 1\\ \\ \\\Longrightarrow \sf 36x - 30 - 35x + 40 = 48 - 12x + 1\\ \\ \\\Longrightarrow \sf x + 10 = 49 - 12x\\ \\ \\\Longrightarrow \sf x + 12x = 49 - 10\\ \\ \\\Longrightarrow \sf 13x = 39\\ \\ \\\Longrightarrow \sf x = \dfrac{39}{13} \\ \\ \\\Longrightarrow \sf x = 3$

Answer: x = 3
