esulting equation after action\ for row 1 will be used again as the \starting equation on this step\ for row 2. step 1 step 2 equations action (in words) \\(x = 0.5\\) \\(x = 4\\) \\(x = 11\\) add 7 to both sides of the equation. \\(x = 14.5\\) \\(x = 16\\) divide both sides of the equation by 2. \\(x = 23\\) \\(x = 33\\) multiply both sides of the equation by 2. \\(x = 37\\) \\(x = 44\\) subtract 7 from both sides of the equation. \\(x + 7 = 7.5\\) \\(x + 7 = 30\\) \\(\frac{x}{2} = 8\\) \\(\frac{x}{2} = 22\\) \\(\frac{x + 7}{2} = 15\\)

Explanation:

Step1: Start with the initial equation

The starting equation is $\frac{x + 7}{2}=15$. To eliminate the denominator, we multiply both sides of the equation by 2.
Action: Multiply both sides of the equation by 2.
Resulting Equation: $x + 7=30$ (since $15\times2 = 30$)

Step2: Solve for x

Now we have the equation $x + 7=30$. To isolate $x$, we subtract 7 from both sides of the equation.
Action: Subtract 7 from both sides of the equation.
Resulting Equation: $x=23$ (since $30 - 7=23$)

Answer:

Step 1:
Starting Equation on This Step: $\boldsymbol{\frac{x + 7}{2}=15}$
Action (in Words): Multiply both sides of the equation by 2.
Resulting Equation After Action: $\boldsymbol{x + 7=30}$

Step 2:
Starting Equation on This Step: $\boldsymbol{x + 7=30}$
Action (in Words): Subtract 7 from both sides of the equation.
Resulting Equation After Action: $\boldsymbol{x = 23}$
