4b+3=9
Subtract 3 from both sides,
4b=6
Divide by 4 on both sides,
b=1.5

Subtract the 3 from both sides of the equation to get the 4b alone on one side of the equation. Now you have 4b=9-3 now subtract to get 4b=6 now divide both sides by 4 to get b=1.5

Which of the following equations has infinitely many solutions? A. 2x + 5(2x + 6) = 12x + 30 B. 2x + 5 = 2 C. 2(x + 5) + 2 = 6x

Nat2105 [25]

Answer:

A. 2x + 5(2x + 6) = 12x + 30

Step-by-step explanation:

Infinitely many solutions means the two sides of the equation will be equal to each other, so B and D can be eliminated. Distribute for A and C to check

A. 2x + 5(2x + 6) = 12x + 30

2x + 10x + 30 = 12x + 30

12x + 30 = 12x + 30

C. 2(x + 5) + 2 = 6x + 2(x + 2)

2x + 10 + 2 = 6x +2x + 4

2x + 12 = 8x + 4

You only get the same equation for A, therefore A is the correct answer
