Answer:
(-3, -4).
Step-by-step explanation:
-4x + y = 8
x - 5y = 17 Multiply this by 4:
4x - 20y = 68 Add this to the first equation:
-19y = 76
y = 76/-19
y = -4.
Plug this into the second equation:
x - 5(-4) = 17
x = 17 - 20
x = -3.
CHECK this result in equation 1:
-4(-3) + -4 = 8
12 - 4 = 8
8 = 8 <------ OK.
Answer:
he needs to know the width!!!
Step-by-step explanation:
since length multiplied by the width equals area,
so since the length is given, the width is needed
So you would use GEMDAS or PEMDAS
-8-1+4x2
-8-1+8
-9+8
-1
