Distribute
x-4x+7= 5x-x-21

Combine like terms
-3x+7= 4x-21

Add 21 to both sides
-3x+28=4x

Add 3x to both sides
28=7x

Divide both sides by 7
4=x

Final answer: x=4

Answer:

Slope = -5/8

Step-by-step explanation:

Take 2 points from the graph where the line is. Point 1: (1 , 6). Point 2: (9 , 1).

We are going to use the formula for finding the slope of a line now.

y2 - y1/x2 - x1 = 1 - 6/9 - 1 = -5/8

Slope = -5/8

The sum of two numbers is
lara [203]
Answer:
The larger number is 60
The smaller number is 14

Explanation:
Assume that the larger number is x and that the smaller number id y.

We are given that:
1- The sum of the two numbers is 74. This means that:
x + y = 74
This equation can be rewritten as:
x = 74 - y .............> I
2- Four times the smaller number (4y) subtracted from the larger number (x), the result would be 4. This means that:
x - 4y = 4 ..............> II

Substitute with I in II and solve for y as follows:
x - 4y = 4
74 - y - 4y = 4
74 - 5y = 4
5y = 70
y = 70/5
y = 14

Substitute with the value of y in equation I to get x as follows:
x = 74 - y
x = 74 - 14
x = 60

Hope this helps :)
