Let x be represent the number of Jerry and x + 11 for Mary.
x = Jerry
x + 11 = Mary
Getting Jerry's number:
x + (x + 11) = 89
2x + 11 = 89
2x = 89 - 11
2x = 78
2x/2 = 78/2
x = 39
Getting Mary's number(simplify):
x + 11
= 39 + 11
= 50
.
Therefore, Mary and Jerry's age are 50 and 39, respectively.

Mary and Jerry's number will be 39 and 50.The sum of their numbers is 89.Which shows that the obtained answer is correct.

What is a linear equation?

It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.

If in the linear equation one variable is present then the equation is known as the linear equation in one variable.

Let, Mary’s number be x

Mary’s number is eleven more than Jerry’s

Jerry's number is x+11

From the given condition sum of their numbers is 89.

[tex]x + (x + 11) = 89\\\\ 2x + 11 = 89\\\\ 2x = 89 - 11\\\\ 2x = 78\\\\ \frac{2x}{2} = \frac{78}{2} \\\\ x = 39[/tex]

Jerry's number will be;

[tex]x+11 \\\\ 39+11 \\\\ 50[/tex]

Hence the Mary and Jerry's number will be 39 and 50.
