Hey there! :D
Make an algebraic expression.
Let the 'number' equal x.
4x-24= 60
Add 24 on both sides.
4x= 84
Divide both sides by 4.
x=21
The number is 21.
I hope this helps!

The given points are: (-2,4) and (6,b)
The slope is -3/2
The slope is the change in Y over the change in x.
So you get: -3/2 = (b - 4) / (6 - -2)
Simplify to get: -3/2 = (b - 4) / 8
Now we see the denominator on the right is 8 and on the left is 2, this is a scale of 4: (8 / 2 = 4) so the numerator on the right needs to be scaled by 4 as well.
The left side is -3, so the right side needs to equal -3 x 4 = -12
Now we know b - 4 = -12, solve for b:
b -4 = -12, add 4 to both sides:
b = -8
Now check:
(-2,4) (6,-8)
Slope = (-8 - 4) / (6 - -2) = -12 /8 = -3/2
b = -8
Answer:
y = -16
Step-by-step explanation:
First lets handle the fractional y's:
This can be reduced down to 2y. That is easier to work with. Next we will rewrite the equation using or new value for y:
35 + 2y = 3
Subtract 35 from both sides:
2y = -32
Next, divide both sides by 2
y = -16
Check our answer:
35 + 
35 -40 + 8 = 3
-5 + 8 = 3
3 = 3
