Question

15.  Solve 3x/4 – 7/4 = 5x + 12

Answer 1

Answer:

x= (-55/17)

Step-by-step explanation:

$\frac{3x}{4} - \frac{7}{4} = 5x + 12 \\ \\ \frac{3x - 7}{4} = 5x + 12 \\ \\ 3x - 7 = 4(5x + 12) \\ 3x - 7 = 20x + 48 \\ 3x - 20x = 48 + 7 \\ - 17x = 55 \\ x = - \frac { 55}{17}$

I hope it helps you

thank you

have a great day

Answer 2

Answer:

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

Step-by-step explanation:

Multiply both sides by 4...

3x-7=20x+48

-17x=48--7=55

x=55/-17
