Question

Jeremy solved the equation 3+x= 11 by drawing a model. Use numbers and words to explain how Jeremy's model can be used to find the solution.

Answer 1

The expression 3 + x = 11 is an equivalent equation of a model

The solution to the equation is x = 8

How to solve the equation

The equation is given as:

3 + x = 11

Subtract 3 from both sides of the equations

-3 + 3 + x = -3 + 11

Evaluate the expression on the right-hand side

-3 + 3 + x = 8

Evaluate the expression on the left-hand side

x = 8

Hence, the solution to the equation is x = 8
