1. If x = -3 , evaluate : 2x + x + 2x + 5 2. 2 ( 2x + 1) + x = x + 2x + 18
3. 2x + x + 2x = 10 + x
Please help thank you in advance :)

1. -10

2.x=8

3. x= 2

Step-by-step explanation:

1. x = 3, 2x+x+2x+5

=2(-3)+(-3)+2(-3)+5

= -6 +(-3)+(-6)+5

= -6 -3 -6 +5 Next you have to use BODMAS rule so first addition

= -6 -3 -1

= -9-1

= -10

2. 2(2x+1)+x=x+2x+18

=4x+2+x=3x+18 then collect like terms:

=4x+x+2=3x+18

=5x+2=3x+18

=5x+2-2=3x+18-2

=5x=3x+16

=5x-3x=3x-3x+16

= 2x=16

2x/2=16/2

x=8

3.2x+x+2x=10+x

=6x=10+x

=6x-x=10+x-x

=5x=10

=5x/5=10/5

x=2

If its helpful ❤❤❤

THANK YOU

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
