Verified step by step guidance1
Distribute the -2 across the terms inside the parentheses: -2(5) + (-2)(-3x) + x = 7x - 10.
Simplify the left side: -10 + 6x + x = 7x - 10.
Combine like terms on the left side: -10 + 7x = 7x - 10.
Subtract 7x from both sides to isolate the constant terms: -10 = -10.
Since the equation simplifies to a true statement without any variables, it is an identity, meaning it is true for all values of x.
