What is the value of x? X-3/7 equals 4

Mathematics

Greeley [361]3 years ago

For this case we must find the value of the variable "x" of the following expression:

\frac {x-3} {7} = 4

So:

We multiply by 7 on both sides of the equation:

x-3 = 4 * 7\\x-3 = 28

We add 3 to both sides of the equation:

x = 28 + 3

Equal signs are added and the same sign is placed.

x = 31

Answer:

x = 31

Step-by-step

X-3/7 = 4

take -3/4 to the other side

x = 3/7 + 4

x = 3/7 + 28/7 (<=another way to write 4)

x = 31/7

What is the slope of the line?
frosja888 [35]

Answer:

Step-by-step explanation:

by inspection.. ( looking at the graph)  we can see that the slope is down hill. so it's going to be negative and also  slope = rise / run     [rise is negative in this question] soo ... i'm looking carefully to see where the line is crossing the grid marks exactly .. it looks like to me  (-3,1) and (2,-3)   you tell me if that looks right... if it does .. then the rise / run is 4/5  and this is a negative slope  sooo  

- 4/5
