Answer:
always true
Step-by-step explanation:
Simplify, and if possible solve the equation to find out
remember, inverse operations
5x - 10 + 2x = 7 + 7x - 17
simplify both sides
7x - 10 = 7x - 10
this is an identity, no matter the value of x put in, the equation will be true,
hence the equation is always true
