To solve the equation ( a + (-17) = 30 ) for the variable ( a ), you need to isolate ( a ) by adding 17 to both sides. This gives you ( a + (-17) + 17 = 30 + 17 ), simplifying to ( a = 47 ). Thus, you should add 17 to both sides of the equation.
Equal quantities may be added to both sides of a linear equation.
