Answer:
(3, 3 )
Step-by-step explanation:
Given the 2 equations
3x - y = 6 → (1)
6x + y = 21 → (2)
Adding the 2 equations term by term will eliminate y, that is
(6x + 3x) + (y - y) = (21 + 6), that is
9x = 27 (divide both sides by 9 )
x = 3
Substitute x = 3 into either (1) or (2) and solve for y
Using (2), then
(6 × 3) + y = 21
18 + y = 21 ( subtract 18 from both sides )
y = 3
Solution is (3, 3 )
The answer is 16 because (-2*-2*-2*-2= 16)
Answer: 18
Step-by-step explanation:
2r+12/n
Plug in the 3 and 7
2(7)+12/3
14+4
18

Answer:
y=(-5/2) x -7
Step-by-step explanation:
y=mx+b
m=(-5/2)
To find b:
3=(-5/2)times"x" + b
3=(-5/2)times(-4) + b
3= 10 +b; b=-7
y=(-5/2) x -7
