robert went to the grocery store and purchased cans of soup and frozen dinners. each can of soup has 300 mg of sodium and each frozen dinner has 500 mg of sodium. robert purchased a total of 14 cans of soup and frozen dinners which collectively contain 5200 mg of sodium. write a system of equations that could be used to determine the number of cans of soup purchased and the number of frozen dinners purchased. define the variables that you use to write the system.

the question is too hard

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!
