Answer:

Step-by-step explanation:

Given

Let the first number = x

Let the second number = 2x + 4

Let the third number = 3x -5

The sum of the three numbers = 101

Equation

x + 2x + 4 + 3x - 5 = 101         Combine like terms on the left

x + 2x + 3x + 4 - 5 = 101        Combine

6x - 1 = 101                             Add 1 to both sides

6x = 101 + 1

6x = 102                                Divide by 6

6x/6 = 102/6

x = 17

Answer

The first number = 17

The second number = 2*17 + 4 = 34 + 4 = 38

The Third number = 3*17 - 5 = 51 - 5 = 46

Check

17 + 38 + 46  = 101

How do i make a equation with infinite solutions?
Igoryamba

Essentially, what you need to do is ensure that both sides cancel each other out to make 0 = 0

An example:

2(x + y) + 4 = (4x + 4y + 8)/2

2x + 2y + 4 = 2x + 2y + 4

0 = 0

The coordinates below represent two linear equations. How many solutions does this system of equations have? Line 1 x y –3 6 3 4
Maksim231197 [3]

Answer

A. Many solution

Step by step explanation

Points on line 1 : (-3, 6) and (3, 4)

Points on line 2: (-6, 7) and  (9, 2)

Now let's find the slope of the line 1

Slope formula = \frac{y2 - y1}{x2 - x1}

Slope of line 1 = (4 - 6) / (3 - (-3)

= -2/(3 + 3)

= -2/6

Slope of line 1 = -1/3

The equation of the line y - y 1 = m(x - x1)

y - 6 = -1/3 (x - (-3))

y -6 = -1/3 (x + 3)

y -6 = -1/3x - 1

y = -1/3x + 5

Slope of line 2 = (2 - 7) / (9 -(-6))

= -5/(9 + 6)

= -5/15

Slope of line 2 = -1/3

The equation of line

y - y1 = m(x - x1)

y - 7 = -1/3(x - (-6))

y - 7 = -1/3(x + 6)

y -7 = -1/3 x - 2

y = -1/3 x + 5

The line 1 and line 2 have the same slopes and the same y-intercept. Both are the same equation. Therefore, there will be many solution.

Answer : A. 0 Solution

Thank you.
