Answer: They are equivalent, and x = -4/7
Step-by-step explanation:
Fist we need to see what the answers to each of these equations are
7 + 5x = 3 - 2x
Subtract 7 on each side
5x = -4 - 2x
Add 2x
7x = -4
X = -4/7
Now the second one
7 + 7x = 3
Subtract 7
7x = -4
X = - 4/7
They are equal and x = -4/7
