omplete the following stepped-out solution to show that −7+[(8⋅m)⋅18]+7 is equivalent to m

1. Start with the expression: -7 + [(8m) * 18] + 7

2. Simplify the expression within the square brackets: 8m * 18 = 144m
3. Substitute the simplified expression back into the original expression: -7 + 144m + 7
4. Combine like terms: -7 + 7 = 0
5. The final simplified expression is: 144m
6. Therefore, -7 + [(8m) * 18] + 7 is equivalent to 144m.
