The sum of two numbers is 526, and their difference is 176. find the two numbers

Step-by-step explanation:

We can write the information as equations. We will use variables x and y to find the two numbers

Equation 1: The sum of two numbers is 526

x + y = 526

Equation 2: The difference is 176

x - y = 176

With two variables and two equations, we can first find one variable by elimination:

(See image)

and then substitute y into either equation to find x:

(See image)

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
