Determine the value of 3(x+6)-7 when x=7

The value is 32. Solution:
3(x + 6)- 7 when x = 7;
3(7 + 6) - 7
= 3(13) - 7
= 39 - 7
= 32

6(x - 6) - 2(x - 3) + 3x

= 6x - 36 - 2x + 6 + 3x

= 4x - 30 + 3x

= 7x - 30

= 6x - 36 - 2x + 6 + 3x

= 4x - 30 + 3x

= 7x - 30

Identify the solution(s) of the system of equations, if any.
-4x - 2y = 12
6y = -12x - 36 **Weegy:** -4X-2y=12
-12X-6Y=36
X=(12+2Y)/-4
substitute x to second equation
-12[(12+2Y)/-4]-6Y=36

The solution(s) of the system of equations : -4x - 2y = 12 6y = -12x - 36 is it has infinite solutions .

-4x - 2y = 12 is equal to -2x - y = 6 ,

6y = -12x - 36 is also equal to -2x - y = 6 ,

so it has infinite solutions .

-4x - 2y = 12 is equal to -2x - y = 6 ,

6y = -12x - 36 is also equal to -2x - y = 6 ,

so it has infinite solutions .

Identify the solution(s) of the system of equations, if any.
x + 5y = 4
2x - 5y = 2 **Weegy:** There are 3 terms here, in this expression x - 5y + 3 + x **User:** Identify the solution(s) of the system of equations, if any.
x + 5y = 4
2x - 5y = 2 **Weegy:** I can't graph it for you, [ but I can give you the information to plot.
Moving x over yields:
5y = 2x + 10
Dividing both sides by five will isolate y:
y = 2/5x + 2
This means that the line has a y-intercept of 2 (it crosses the y axis at 2) and a slope of 2/5 (or moves 5 x units for every 2 y units). ] **User:** Identify the solution(s) of the system of equations, if any.
4x + 2y = 4
y = 3 - 3x **Weegy:** 4x - 4y = 10 divided by 2 on both sides the result is: 2x - 2y = 5 (equ. 1) 3x + 2y = 5 (equ. 2) adding up equations 1 and 2 the result is: 5x = 10 x = 10/5 = 2 4(2) - 4y = 10 -4y = 10 - 8 = 2 y = 2/-4 = -1/2 The solution for the system 4x - 4y = 10 3x + 2y = 5 is (2, -1/2) (More)
