Answer:
(-2,8)
Step-by-step explanation:
3x+3y = 18
2x+y = 4
Multiply the second equation by -3
-3(2x+y) = -3*4
-6x-3y = -12
Add this to the first equation
-------------------------
-3x = 6
Divide each side by -3
-3x/-3 = 6/-3
x = -2
Now solve for y
2(-2) +y = 4
-4+y =4
Add 4 to each side
-4+4+y = 4+4
y =8
3x + 3y = 18 (1)
2x + y = 4 (2)
(1) - 3(2)
3x + 3y = 18
-(6x + 3y = 12)
Using (2)
2(-2) + y = 4
-4 + y = 4
y = 8
Answer: Say what is this
The answer is A) -9.272
-5.872 + (-5.1)/1.5
= -5.872 - 3.4
= -9.272
