+1. Y = 5x + 1;				Invalid because "5x" needs *
+2. x^2 + 2x + 1 = 0;		Invalid because "2x" and because the left side of the equal sign should just be a variable location and you cannot use exponents 
+3. X = 5 * a + 4;			Valid
+4. 0 = -15 * b;				Invalid because "0" (left side of equal sign must be a variable)
