Answer:
Step-by-step explanation:
-10 ( y-4) + 3y = 5 <--- substitute the value of x into first equation
-10y + 40 + 3y = 5
-7y + 40 = 5
-7y = -35
y= 5
x = 5 - 4
x = 1
Answer:
7y+4x
Step-by-step explanation:
1. So the -y is 1 so you subtract one from the 8 which is 7.
2. x is also like a one so that would also equal 4
Answer:
-9n + 36
Step-by-step explanation:
1. -9(n - 4) -Distribute
2. -9n + 36 -Answer
Answer:
Step-by-step explanation:
the y intercept determines where you are going to start and then your m or your slope tells you how many units up or down and left and right you are going to go or you rise over run in this case 2/1
so you start at (0,2) and then move 2 up and one to the right
and you go 2 units down and 1 to the left
ANSWER:
The solution for this problem is displayed in the attached image. I have made the numbers ( answers ) which I inputed into the table bold and red.
The method I used to solve this problem was trial and error.
To check the answers, you must simply input the numbers with each of the symbols into the equations. If the left-hand side of the equation is equivalent to the right-hand side of the equation, the equation is correct.
COLUMNS -
Column No. 1:
5 + 4 - 7 = 2
9 - 7 = 2
2 = 2
Therefore, this equation is correct.
Column No. 2:
9 ÷ 1 + 6 = 15
9 + 6 = 15
15 = 15
Therefore, this equation is correct.
Column No. 3:
3 × 8 ÷ 2 = 12
24 ÷ 2 = 12
12 = 12
Therefore, this equation is correct.
ROWS -
Row No. 1:
5 × 9 ÷ 3 = 15
45 ÷ 3 = 15
15 = 15
Therefore, this equation is correct.
Row No. 2:
4 - 1 × 8 = 24
3 × 8 = 24
24 = 24
Therefore, this equation is correct.
Row No. 3:
7 - 6 + 2 = 3
1 + 2 = 3
3 = 3
Therefore, this equation is correct.
Since all equations in this problem are correct, this means that all the numbers ( answers ) must also be correct.
