Answer:
(42-24n)
Step-by-step explanation:
(7-4n)×6
take the 6 and multiply it to the integers in the paraenthesis.
so you take the ouside number which is 6 and multiply it with the first number which is 7 in the paraenthesis.
6×7=42
(42-4n)
then take the next number 4n and multiply by 6
4n × 6 = 24n
finally put it all together
(42-24n)

y=13
Step-by-step explanation:
-3x+2y=56
-5x-2y=24
so first we want to get rid of one variable, in this example we dont need to multiply because the y's cancel out
so we have
-8x=80
x=-10
now plug in x into an original equation
-3(-10)+2y=56
2y=26
y=13
hope that helps
