Answer 1

Ответ:

50x-2x=0

48x=0

X=0:48

X=0

(5+4b)(4b-5)=0

5+4b×4b-5=0

4b×4b=5-5

16b=0

b=0:16

b=0

(2a+3)=0

2a+3=0

a=3-2

a=1

3x-48=0

x=48:3

x=16

Answer 2

The given expression seems to be a combination of equations and expressions. Let's break it down and analyze each part individually:

1. 50x - 2x = 0 This is a simple equation. We can combine like terms on the left side: 48x = 0 Dividing both sides by 48, we get: x = 0

2. (5 + 4b)(4b - 5) = 0 This is a quadratic equation in the form of a product of two binomials. To find the values of b that satisfy this equation, we can use the zero product property, which states that if a product of factors is equal to zero, then at least one of the factors must be zero. So we set each factor equal to zero and solve for b: 5 + 4b = 0 --> 4b = -5 --> b = -5/4 4b - 5 = 0 --> 4b = 5 --> b = 5/4

Therefore, the values of b that satisfy the equation are b = -5/4 and b = 5/4.

3. (2a + 3) = 3x - 48x = 0 This expression is a combination of two equations separated by an equal sign. Let's solve each equation separately:

2a + 3 = 0 Subtracting 3 from both sides: 2a = -3 Dividing both sides by 2: a = -3/2

3x - 48x = 0 Combining like terms on the left side: -45x = 0 Dividing both sides by -45: x = 0

Therefore, for this expression, a = -3/2 and x = 0.

To summarize: For the given expressions and equations:

• In the equation 50x - 2x = 0, x = 0.
• In the quadratic equation (5 + 4b)(4b - 5) = 0, b = -5/4 and b = 5/4.
• In the equation (2a + 3) = 3x - 48x = 0, a = -3/2 and x = 0.
