() = Fraction

Answer:

1. x= −(3 /5 y)+ (23 /5)

2. x=−2y+6

Step-by-step explanation:

Let's solve for x.

5x+3y=23

Step 1: Add -3y to both sides.

5x+3y+−3y=23+−3y

5x=−3y+23

Step 2: Divide both sides by 5.

5x /5 = −((3y+23) /5)

x= −(3 /5 y)+ (23 /5)

------------------------------------------------

Let's solve for x.

2x+4y=12

Step 1: Add -4y to both sides.

2x+4y+−4y=12+−4y

2x=−4y+12

Step 2: Divide both sides by 2.

(2x /2 )= −((4y+12) /2)

x=−2y+6

Hope it helped!

Find the value of x.
Travka [436]
In order to solve you must find the value of the blank angle. 
Here is your first equation.
126 + x = 180
Subtract 126 from both sides.
x = 54
So now add up all the angles.
x + (2x + 6) + 54 = 180
Combine like terms.
3x + 60 = 180
Subtract 60 from both sides.
3x = 120
Divide.
x = 40
Now check your answer.
40 + 2(40) + 6 + 54 = 180
40 + 80 + 6 + 54 = 180
120 + 60 = 180
180 = 180 
There is a solution. The answer is 40.
I hope this helps love! :)
