3x + y = 17<br> 4x - y = 18
Inessa05 [86]
The two equations given are
3x + y = 17 and 4x - y = 18
Now we will first take one equation
3x + y = 17
Then
y = 17 - 3x
Now replacing the value of y in the second equation we get
4x - y = 18
4x - (17 - 3x) = 18
4x + 3x - 17 = 18
7x = 35
 x = 35/7
   = 5
Putting the value of x in the first equation we get
3x + y = 17
(3 * 5) + y = 17
15 + y = 17
y = 17 - 15
y = 2
So the value of x is 5 and y is 2

The difference between eight times a number and three is equal to negative nineteen. What is the number?
Alex777 [14]

Answer:

The number is -2.

Step-by-step explanation:

From the word problem, we can figure out the equation for the unknown number (x).

8x-3=-19

We would then work out the equation to find x.

Add 3 to -19.

8x=-16

Divide -16 by 8.

x=-2

Answer:

9

Step-by-step explanation:

We put 237 in I,

3 in J,

10 in T,

4 in H

4 in M

Leave s as is because that's what we want to find.

I = 100+12J+5T+7S+5H-8M\\237 = 100+12(3)+5(10)+7S+5(4)-8(4)\\237=100+36+50+7S+20-32\\237=7S+174\\7S=237-174\\7S=63\\S=9
