Step-by-step explanation:
Answer:
Less than.
Step-by-step explanation:
Because they have the same denominator, you can ignore them and just look at the numerator. 4 < 6.
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: -8y+12
Step-by-step explanation: Multiply using the distributive property.
Hope this helps.
