Answer:

x=3

Step-by-step explanation:

1)  3(x+7)=6(x+2)

2)Multiply the number on the outside by the numbers on the inside

 3x+21 =6x+12

3)Subtract 3x from 6x. When you do that it cancels out itself on the side it came from leaving you with only 21 one that side.

21=3x+12

4)Subtract 12 from 21. When you do that it cancels out itself on the side it came from leaving you with only 3x on that side.

9=3x

5)  Divide 3x from both sides that will cancel out the x leaving you with only 1x and it will turn the 9 into 3.

9/3x=3x/3x

x=3

Which point satisfies the system of equations y = 3x − 2 and y = -2x + 3?
Sedbober [7]

Answer:

(1,1)

Step-by-step explanation:

The choices are not visible, however are unnecessary to solve this problem.

Given y = 3x - 2 and y = -2x + 3

[Set them equal to each other]

3x - 2 = -2x + 3

[Find x]

3x + 2x - 2 = 3

3x + 2x = 5

5x = 5

x = 1

[Plug x = 1 to both equations to check and find y]

y = 3x - 2

y = 3(1) - 2 = 3 - 2 = 1

y = -2x + 3

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

Both are equal to y = 1 when x = 1

The point is then: (1,1)
