Solve the system of equations:<br> y = x-4<br> -2x + y = 18

Pie

Answer:

x = 7.3

Step-by-step explanation:

-2x + x-4 = 18

First, Combine Like Terms

-3x + (-4) = 18

Then, do Inverse Operations

-3x + -4 = 18

+ 4 +4

Cancel out the -4 +4 because it will equal zero and won't matter to the equation

-3x = 22

Do Inverse Operations again. In this case, you will divide.

-3x = 22

-3x/-3 = 22/-3

Cancel out the -3x/-3

22/-3 = x

7.3 = x

The sum of two numbers is 57. The larger number is 11 more than the smaller number. What are the numbers?

FromTheMoon [43]

Answer:

I'll tell u later

Step-by-step explanation:

Small number =x

Large number =11 plus x

Now from the question,

$x + 11 + x = 57$

Therefore 2x plus 11= 57

2x= 57-11=46

X=46÷2=23
