205 d. Re-write the two equations from parts (b) and (c). This is a system of linear equations. Solve the system by using either the substitution method (useful if it's easy to make one equation look like x=…… or y=.…) or the addition method (useful if the equations are in standard form Ax+ By =C,and it's easy to determine a plan to cancel a variable when adding multiples of the equations together). For an application (word problem) do not express the solution as a set. Refer to part (a). What does each variable mean? Write a brief sentence answering the question posed in the problem. Be sure to attach the appropriate unit to each number value.

4. Jeffrey and Robert are very hungry after working out. For lunch, Jeffrey has two slices of
veggie lover's pizza and one slice of plain pizza for a total of 858 calories. Robert has two
slices of plain pizza and one slice of veggie lover's pizza for a total of 846 calories. Write and
solve a system of linear equations to find the number of calories in one slice of veggie
lover's pizza and the number of calories in one slice of plain pizza.
a. What are the two quantities you are asked to find? Be specific. Label one of the quantities
x, and the other y (or choose your own variables.)
b. Focus on the phrase, "...Jeffrey has two slices of veggie lover's pizza and one slice of plain
pizza for a total of 858 calories". Think about the meaning of x and y from part (a) and
then write an equation containing the variables and the "total" number.
C. Focus on the phrase, "Robert has two slices of plain pizza and one slice of veggie lover's
pizza for a total of 846 calories". Think about the meaning of x and y from part (a), and
then write an equation containing the variables and the "total" number.
