Question

1. consider the equation 42a - 26 = 436. select the first step used to start solving the equation. given 42a - 26 = 436 42a = 436 + 26 add 26 to both sides of the equation divide both sides of the equation by 26 subtract 26 from both sides of the equation multiply both sides of the equation by 26

Explanation:

To solve the equation \(42a - 26 = 436\), we want to isolate the term with the variable (\(42a\)) first. The inverse operation of subtraction is addition. So, we add 26 to both sides of the equation to cancel out the \(-26\) on the left side. This gives us \(42a - 26 + 26 = 436 + 26\), which simplifies to \(42a = 436 + 26\). So the first step is to add 26 to both sides of the equation.

Answer:

Add 26 to both sides of the equation
