Final answer:
The first step in solving an equation for x would be to perform an operation that simplifies the equation, such as adding or subtracting a term on both sides. The exact operation depends on the form of the equation being presented.
Step-by-step explanation:
To solve the equation, we would need to know the exact equation in question. However, using the reference given, typically the first step when solving linear equations involves simplifying the equation or isolating the variable . If the equation contains a term with the variable on one side that is added or subtracted, you would perform the inverse operation to both sides to move that term across the equality. It sounds like you may want to either add or subtract a value from both sides. Without the specific equation, it's not possible to determine whether we should add 1.9, add 0.2, subtract 0.2, or perform some other operation as the first step.
Once the variable is isolated on one side, you can proceed with solving for by performing operations such as division or multiplication to both sides of the equation to get by itself.
