Answer:

The temperature yesterday was 36 °C.

Step-by-step explanation:

I am going to solve this question building a system of equations.

We have that:

x is the temperature last week at the lake.

y is the temperature yesterday at the lake.

Last week at the lake it was 23 °C.

This means that x = 23

Yesterday it was 13 degrees warmer.

This means that

y = x + 13

Since x = 23

y = 23 + 13 = 36

The temperature yesterday was 36 °C.
