Question

In this figure shown below, for what value of h will XY - X Z? Four students worked out the problem. Choose the student that solved for h correctly.

Answer 1

Step-by-step explanation

In order to get the congruency, we need to match both sides:

`XY=XZ`

Substituting terms:

`7h-5=3h+5`

Subtracting -3h to both sides:

`7h-3h-5=5`

Subtracting like terms:

`4h-5=5`

Adding +5 to both sides:

`4h=10`

In conclusion, the appropriate expression is the Student C
