Step-by-step explanation:
16+13q
Answer:
A
Step-by-step explanation:
we can conclude from the second equation that when
2x + y = 6 then y = 6 - 2x. so instead of y in the first equation we use 6 - 2x.
now the equation would look like this : 6 - 2x = x^2 - 4x + 3 .
then we bring everything to one side of the equation : x^2 - 2x - 3 .
now we'll have two results for x ( because x^2 - 2x - 3 = 0 has 2 answers )
one of them is -1 and other one is 3.
if we put them in the first equation we will have 8 and 0 for y.
so A is the answer
Answer: d.) 3.6x + 6.1
Step-by-step explanation:
Combine like terms
6.4x + 3.1 + (-2.8x) + 3
(6.4x - 2.8x) + (3.1 + 3)
3.6x + 6.1
