Answer:

x=1

Step-by-step explanation:

I will solve your system by substitution.

(You can also solve this system by elimination.)

3x−2y=1;2x+2y=4

Step: Solve3x−2y=1for x:

3x−2y+2y=1+2y (Add 2y to both sides)

3x=2y+1

x 3 = 2y+1 3  (Divide both sides by 3)

x= 2 3 y+ 1 3

Step: Substitute  2 3 y+ 1 3 for xin 2x+2y=4:

2x+2y=4

2( 2 3 y+ 1 3 )+2y=4

10 3 y+ 23 =4 (Simplify both sides of the equation)

10 3 y+ 2 3 + −2 3 =4+ −2 3  (Add (-2)/3 to both sides)

10 3 y= 10 3

10 3 y 10 3 = 10 3 10 3  (Divide both sides by 10/3)

Step: Substitute 1 for yin x= 2 3 y+ 1 3 :

x= 2 3 y+1 3

x= 2 3 (1)+ 1 3

x=1 (Simplify both sides of the equation)

That was a lot to type.

Solve each system by elimination.
strojnjashka [21]

Answer:

y = -1, x = -2

Step-by-step explanation:

First, multiply the top equation by 2 to make 3x become 6x:

6x - 8y = -4

Second, multiply the bottom equation by 3 to make -2x become -6x:

9y - 6x = 3

Add the two equations together, and you get:

y = -1

Plug in y as -1 into the first or second equation:

3x - 4(-1) = -2

OR

3(-1) - 2x = 1

x = -2

What is the value of X?
andrezito [222]

Solution:

<u>Note that:</u>

  • 3x + 50 = 6x - 10 (Vertically opposite angles)

Simplify the equation to find x.

<u>Add 10 both sides.</u>

  • 3x + 50 = 6x - 10
  • => 3x + 50 + 10 = 6x - 10 + 10
  • => 3x + 60 = 6x

<u>Subtract 3x both sides.</u>

  • 3x + 60 = 6x
  • => 3x - 3x + 60 = 6x - 3x
  • => 60 = 3x

<u>Divide 3 both sides.</u>

  • 60 = 3x
  • => 60/3 = 3x/3
  • => x = 20
