Answer:

Options (A), (C) and (E)

Step-by-step explanation:

Given equation is,

-3x + 7 = -5 + x

-3x + 7 - 7 = -5 + x - 7

-3x = -5 + x - 7 Option (C)

-3x = x - 12

-3x - x = -12

-4x = -12 Option (A)

4x = 12 Option (E)

$\frac{4x}{4}=\frac{12}{4}$

x = 3

Therefore, Options (A), (C) and (E) are the correct options.

worty [1.4K]

Answer:

What is 67/7 as mixed number

monitta

Answer:

9 4/7

Step-by-step explanation:

First, we need to make as many 7s as possible. If we do 67/7, we will get 9...... so our whole number is 9. If we do 7 x 9, we get 63 and if we subtract 63 from 67, we are left with 4. All in all, we will get 9 4/7!
