Pls pls me! solve the equation then find out how many solutions are to it! (infinite solution, one solution, or no solution)!

1: 10+6x=2(5+3x)?

2: 3x+5-x=2x+7?

3: 4x-4=2x+8?

answer the equation then find out how many solutions there are!

pls i need a good grade!

Number one: Infinite solutions

Number two: No solutions

Number three: X=6

Step-by-step explanation:

Number one:

10+6x=2(5+3x)

10+6x=(2)(5)+(2)(3x)(Distribute)

10+6x=10+6x

6x+10=6x+10

Step 2: Subtract 6x from both sides.

6x+10−6x=6x+10−6x

10=10

Step 3: Subtract 10 from both sides.

10−10=10−10

0=0

Number two:

Step 1: Simplify both sides of the equation.

3x+5−x=2x+7

3x+5+−x=2x+7

(3x+−x)+(5)=2x+7(Combine Like Terms)

2x+5=2x+7

2x+5=2x+7

Step 2: Subtract 2x from both sides.

2x+5−2x=2x+7−2x

5=7

Step 3: Subtract 5 from both sides.

5−5=7−5

0=2

Number three:

Step 1: Subtract 2x from both sides.

4x−4−2x=2x+8−2x

2x−4=8

Step 2: Add 4 to both sides.

2x−4+4=8+4

2x=12

Step 3: Divide both sides by 2.

2x2=122

x=6

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true
