Solution:
The problem is based on linear equations in one variable.
Let's transpose the terms in the given equation
3x + 5 = 2x - 7
3x - 2x = -7 - 5 → shifting the terms from LHS to RHS and vice-versa.
x = -12
Thus, -12 is the solution for 3x + 5 = 2x - 7.
Summary:
The solution of 3x + 5 = 2x - 7 is x = -12.
