How do I solve this math problem. -2-10a=158
-2-10a=158
-10a = 160
a = -16
To solve the equation -2 - 10a = 158, follow these steps:
Step 1: Begin by isolating the variable term. In this case, the variable term is -10a. To do this, add 2 to both sides of the equation:
-2 - 10a + 2 = 158 + 2
-10a = 160
Step 2: Next, divide both sides of the equation by -10 to solve for 'a'. Note that dividing an equation by a negative value reverses the inequality.
-10a / -10 = 160 / -10
a = -16
So, the solution to the equation is a = -16.
