Answer:
the solution is x = 2 and y = 4 OR (2,4)
Step-by-step explanation:
From the question
Equation 1: 3x-2y= -2
Equation 2: 3x + y = 10
Subtract equation 1 from equation 2, that is
3x + y = 10 - (3x -2y = -2)
You get
3x - 3x + y - (-2y) = 10 - (-2)
0 + y + 2y = 10 + 2
3y = 12
Divide both sides by 3
∴ y = 12/3
y = 4
Substitute the value of y into equation 2 to get x
3x + y = 10
3x + 4 = 10
Then,
3x = 10 - 4
3x = 6
Divide both sides by 3
∴ x = 6/3
x = 2
Hence, the solution is x = 2 and y = 4
Answer:
126in
Step-by-step explanation:
6*5=30
5*3=15
6*3=18
30+15+18 = 63
63*2=126
Answer:
75
Step-by-step explanation:
If the third of 6 consecutive numbers is 12, what is their sum?
6 numbers = c-2, c-1, c, c+1, c+2, and c+3
The numbers become 10, 11, 12, 13, 14, and 15
Add that together and you get 75.
