, i need solve the following system of equations: 2x − y + z = −3 2x + 2y + 3z = 2 3x − 3y − z = −4 a. (1, 3, 2) b. (−1, 3, 2) c. (1, −3, 2) d. (1, 3, −2)

Your answer is B love

don't give

take it once

try and try and you will not

happy to

pls mark as brainliest

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
