To solve a literal equation, you need to isolate the variable in the equation. Here's how you can do it step-by-step:
Step 1: Start by identifying the variable you want to solve for. In this case, we want to solve for "x."
Step 2: Look for any terms or constants that are combined with the variable. In the given equation, we have the term "3x" on the left side.
Step 3: To isolate the variable, we need to get rid of any terms or constants that are combined with the variable. In this example, we subtract 5 from both sides of the equation to remove the "-5" term:
3x - 5 - 5 = 9 - 5
3x - 10 = 4
Step 4: After removing the term combined with the variable, we can rearrange the equation so that all the terms are on one side and the constants are on the other side. In this case, we move the constant to the other side by adding 10 to both sides of the equation:
3x - 10 + 10 = 4 + 10
3x = 14
Step 5: Lastly, to solve for "x," divide both sides of the equation by the coefficient of "x" (which is 3 in this case):
(3x)/3 = 14/3
x = 14/3
So, the solution to the given equation is x = 14/3.
From your example, it seems like you already have the solution for "x" as -1, 0, and 1. To verify whether these solutions are correct, you can substitute each value back into the original equation and see if it satisfies the equation.
