Solve (Temperature Increase)

Lesson Page 3, Section 1

What you'll work on

Solve a one-step equation by subtracting the starting value from both sides to find how much a quantity increased.

Big Idea for this lesson

$A tall painted classical mercury thermometer standing against a warm amber background, with a red mercury column rising from a low point to near the top of the bulb, and a soft painted curly bracket beside the column highlighting the height the mercury has climbed — classical-education aesthetic, no text, no numbers.$

To find an increase, subtract the starting value from the ending value. When you see 'starting + x = ending,' subtract the starting amount from both sides — and x appears.
