Question

Create an algebraic expression with at least 2 variables, 2 different operations and a constant.

Choose values for all your variables but you must include at least one fraction or decimal number.


Lastly, Evaluate your expression showing all steps.

Answer 1

let's choose

5x+3x-7y+2x-16y+3+-5y

1) give values to our variables:

x=3

y=4

so

5(3)+3(3)-7(4)+2(3)-16(4)+3-5(4)

15+9-28+6-64+3-20

1) first take this step-by-step and solve each term from left-right

15+9=24

24-28=-4

-4+6=2

2-64=-62

-62+3=-59

-59-20=-79

-79 is the answer
