The option "Multiply both sides by 7" (4 of 11) has been selected. Press tab to choose a response area, and spacebar to insert it. Press escape to cancel.
Step 1: Combine like terms on the left side of the equation.
Reasoning: We want to simplify the equation by combining the terms that have the same variable, in this case, n.
Simplified equation: 7n + 9 = 2
Step 2: Subtract 9 from both sides of the equation.
Reasoning: We want to isolate the variable, n, on one side of the equation.
Simplified equation: 7n = -7
Step 3: Divide both sides of the equation by 7.
Reasoning: We want to solve for the variable, n.
Simplified equation: n = -1
Step 1: The reasoning is to simplify the equation by combining like terms on each side of the equation.
Step 2: The simplified equation is 7n + 9 = 2.
