Question

how can you isolate the variable h?
2(h + 3.5) = -11
2h + 7 = -11

• 7 - 7 ←——————————————————— subtract 7 on both sides.

2h = -18 ? ? on both sides.

Explanation:

Step1: Identify the operation

We have the equation \(2h = -18\). To isolate \(h\), we need to perform the inverse operation of multiplication (since \(h\) is multiplied by 2). The inverse of multiplication is division.

Step2: Perform the operation

Divide both sides of the equation \(2h=-18\) by 2. So the operation is "Divide" and the number is "2".

Answer:

Divide, 2
