Multiply the first equation by -1 to get -4x - y = --5
Then add the second equation 3x + y = 3
+ ____________
-x = -2 or x = 2
then plug in 2 for x in one of the equations and solve for y 4(2) + y = 5
8 + y = 5
Subtract 8 from both sides y = -3
So x = 2, y = -3 or (2,-3)
Answer:
x/2
Step-by-step explanation:
2/2=1=y
4/2=2=y
6/2=3=y
49–2ax –a^2–x^2
Extract the negative sign
= 49 - (a^2 +2ax +x^2)
Factor using a^2 + 2ab + b^2 = (a+b)^2
= 49 - (a+x)^2
Factor using a^2 - b^2 = (a-b)(a+b)
= ( 7- (a + x)) * (7 + (a + x))
= ( 7- a - x) * (7 + a + x)
Answer:
x + 3
Step-by-step explanation:
if x represents a number then 3 more than the number means addition of 3 to the number ( x )
so, required phrase is ;
=》x + 3
Answer:
18 tablespoons of honey
Step-by-step explanation:
Since you need 3 tablespoons of honey for 3 loaves and you know you need 24 loaves you could do...
24/4 which equals 6
You can do this since there's 4 loaves made per 3 tablespoons of honey
Then you could do..
3x6
which gives you 18 tablespoons of honey
