Question

how can you isolate the expression 2h?
2(h + 3.5) = -11
2h + 7 = -11 ? on both sides.
options: add, subtract, multiply by, divide by

Explanation:

Step1: Identify the equation

We have the equation \(2h + 7=- 11\) and we want to isolate \(2h\).

Step2: Recall inverse operations

To isolate \(2h\), we need to get rid of the \(+7\) on the left - hand side. The inverse operation of addition is subtraction. So we should subtract 7 from both sides of the equation. If we subtract 7 from the left - hand side (\(2h + 7-7=2h\)) and subtract 7 from the right - hand side (\(-11 - 7=-18\)), we will be left with \(2h=-18\).

Answer:

Subtract, 7
