12 x = 6
x = 6 / 12
x = 0.5

Check 12 * 0.5 = 6

Solve the system of equations using substitution y=x-1 and y=-2x+5
pav-90 [236]
Since the two equations equal y, set them equal to each other.

x-1=-2x+5

From there, solve for x.

First get x on one side, by using the addition property of equality.

x-1=-2x+5
3x-1=5

Isolate x by adding 1.
3x=6

Lastly get x all by itself by dividing each side by 3.
x=2

You can now substitute your x-value, 2, into one of the equations (or both, if you wish; either one will result in the same answer.)

y=x-1
y=2-1
y=1

OR

y=-2x+5
y=-2(2)+5
y=-4+5
y=1

Final answer:
x=2 and y=1

Any questions or anything you would like me to clarify, feel free to ask :)

Can someone help me with this 2 step eqaution
Snowcat [4.5K]
The answer is:  " 40 books " .
____________________________________________
Explanation:
____________________________________________
Let "x" equal the number of books that Jill started with.  Solve for "x" :
____________________________________________
         x – (1/2)x  + 16 = 36 ;

1x – (1/2)) = (1/2)x ; 

(1/2)x + 16 = 36 ; 

Subtract "16" from EACH SIDE of the equation:

(1/2)x + 16 – 16 = 36 – 16  ; 

(1/2)x = 20 ; 

Multiply each side of the equation by "2" ; 

2*(1/2)x = 20 * 2 ; 

to get:  x = 40 .

The answer is:  " 40 books " .

For this case we have the following equation:
 d =  \sqrt{\frac{3h}{2}}
 Where,
 d: the distance they can see in thousands
 h: their eye-level height in feet
 For Kaylib:
 d = \sqrt{\frac{3(48)}{2}}
 d=\sqrt{3(24)}
 d=\sqrt{72}
 d=6\sqrt{2}
 For Addison:
 d = \sqrt{\frac{3(85\frac{1}{3})}{2}}
 d = \sqrt{\frac{256}{2}}
 d=\sqrt{128}
 d=8\sqrt{2}
 Subtracting both distances we have:
 8\sqrt{2} - 6\sqrt{2} = 2\sqrt{2}
 Answer:
 
2\sqrt{2}

What is the value of x in the equation below?
zubka84 [21]
First you multiply 6(x) then you multiple 6(8)

Your equation should now look like this: 6x-48=72

Subtract 48 from both sides

Your equation should now look like 6x=120

Divide by 6

Answer is 20
