I am really bad at Math, does anyone know how many solutions are in these 1. 2x - x + 7 = x +3 + 4 2. -2(x + 1) = -2x + 5 3. 4x + 2x + 2 = 3x - 7 4. 4(2x + 1) = 5x + 3x + 9 5. X + 2x + 7 = 3x - 7

Step-by-step explanation:

1. 2x - x + 7 = x +3 + 4

Collecting like terms;

2x - x - x = 3 + 4 - 7

2x = 0

x = 0

2. -2(x + 1) = -2x + 5

Expanding the bracket;

- 2x - 2= - 2x + 5

Collecting like terms;

- 2x + 2x = 5  + 2

0 = 7

It has no solution

3. 4x + 2x + 2 = 3x - 7

Collecting like terms;

4x + 2x + 3x = - 7 -2

9x = -9

x = -1

4. 4(2x + 1) = 5x + 3x + 9

Expanding the bracket

8x + 4 = 5x + 3x + 9

Collecting like terms

8x - 5x - 3x = 9 - 4

0 = 5

It has no solution

5. X + 2x + 7 = 3x - 7

Collecting like terms

x + 2x - 3x = - 7 - 7

0 = - 14

It has no solution

glide reflection.

its mainly because the pattern will be infinite and will never end. it will look like a gilder or like a filpbook when set to motion.

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )
