3x/4-7/4=5x+12
​

Answer 1

$\huge\mathfrak\blue{QUESTION}$

SOLVE:

$\frac{3x}{4} - \frac{7}{4} = 5x + 12$

$\huge\mathbb\blue{ANSWER}$

$\frac{3x}{4} - \frac{7}{4} = 5x + 12$

$\frac{3x - 7}{4} = 5x + 12$

$3x - 7 = 4(5x + 12)$

$3x - 7 = 20x + 48$

$3x - 20x = 48 + 7$

$- 17x = 55$

$x = \frac{ - 55}{17}$

$\huge\mathbb\purple{SO FINAL ANSWER}$

$\frac{ - 55}{17}$

Answer 2

Step-by-step explanation:

=5x+12

\frac{3x - 7}{4} = 5x + 12

3x−7

=5x+12

3x - 7 = 4(5x + 12)3x−7=4(5x+12)

3x - 7 = 20x + 483x−7=20x+48

3x - 20x = 48 + 73x−20x=48+7

- 17x = 55−17x=55

x = \frac{ - 55}{17}x=
