What is another way to write 7/8x+3/4=-6

Bess [88]

Answer:

$7x + 6 = - 48$

Step-by-step explanation:

The given expresion is

$\frac{7}{8}x + \frac{3}{4} = - 6$

We multiply through by 8 to get:

$8 \times \frac{7}{8}x + 8 \times \frac{3}{4} = - 6 \times 8$

We cancel out to obtain:

$7x + 2 \times 3 = - 6 \times 8$

We simplify to obtain:

$7x + 6 = - 48$
