Let the number be x
<span>Then According to the equation : </span>
<span>2(X-4)=3(x+5) </span>
<span>2X-8=3X+15 </span>
<span>-23=3X-2X </span>
<span>X=-23</span>
Hello! :)
Answer:
*The answer must have a POSITIVE sign!*
Step-by-step explanation:
Expand with distributive property: a(b+c)=ab+ac
4*5=20
6*4=24
20x-24
2*8=16
2*10=20
16x+20
20x-24=16x+20
First, you add by 24 both sides of an equation.
20x-24+24=16x+20+24
20x=16x+44
You subtract by 16x both sides of an equation.
20x-16x=16x+44-16x
4x=44
Then, you divide by 4 both sides of an equation.
4x/4=44/4
Divide by the numbers from left to right.
44/4=11
<u><em>X=11 is the final answer</em></u>
Hope this helps!
Have a nice day! :)

Thanks!
The generic equation is:
y-yo = m (x-xo)
Where,
m = (y2-y1) / (x2-x1)
m = (0-1) / (4-3)
m = (- 1) / (1)
m = -1
The ordered pair is:
(xo, yo) = (4, 0)
Substituting values:
y-0 = -1 * (x-4)
y = -x + 4
Answer:
y = -x + 4
option 1
Step-by-step explanation:
Howdy, did you do a, b, and c by yourself? Because there are some slight issues, so I'll do my best to explain.
a. 3x+5x
We know that x=2, so we can substitute 2 in for x right now, or we can combine like terms.
3x and 5x both have the variable x so we can add them easily to get 8x. If you substitute in 2, you're just multiplying 8×2, which is 16.
b. 5z+4z+z
Again, since
we know that z=-3, we can substitute in now, or we can combine like terms first. 5z, 4z, and z all have the variable x, we addition is easy. 5+4+1=10, so you'll have 10z. Substitute in -3 for z, and you're just multiplying 10×-3=-30
c. 3x+6+5x
This is trickier since 6 doesn't have the variable x. So to combine like terms means to only add 3x and 5x. So the equation will turn out looming like 8x+6. now substitute in 2 for x and you get
8(2)+6
16+6
22
d. 8y+8-4y
Combine like terms
4y+8
substitute in 5 for y
4(5)+8
20+8
28
e. 5z-4z+z
combine like terms
z+z
2z
substitute -3 for z
2(-3)
-6
f. 3x+6+5x-2
combine like terms
(so that's 3x+5x and 6-2)
8x+4
substitute in 2 for x
8(2)+4
16+4
20
g. 8y+8-4y-3
combine like terms
8y-4y+8-3
4y+5
substitute in 5 for y
4(5)+5
20+5
25
h. 5z-4z+z-3z
combine like terms
-z
substitute in -3 for z
-(-3)
double negatives make a positive
