Answer:
One of the possible dimensions of the full trailer could be 5 by 12 by 3.
Step-by-step explanation:
Volume = weight times height times length = 12 times 5 times 3 = 180.
-3y = x...so we sub in -3y for x in the other equation
-x + 7y = 70
-(-3y) + 7y = 70
3y + 7y = 70
10y = 70
y = 70/10
y = 7
so we sub in 7 for y in either of the original equations to find x
-3y = x
-3(7) = x
-21 = x
so ur solution is (-21,7)
