4x - 5 - 2x = x - 5<br><br> No Solution<br> X=0<br> X=4<br> X=5
Alekssandra [29.7K]

Answer:

x = 0

Step-by-step explanation:

Step 1: Write equation

4x - 5 - 2x = x - 5

Step 2: Solve for <em>x</em>

  1. Combine like terms: 2x - 5 = x - 5
  2. Subtract x on both sides: x - 5 = -5
  3. Add 5 to both sides: x = 0

Step 3: Check

<em>Plug in x to verify it's a solution.</em>

4(0) - 5 - 2(0) = 0 - 5

0 - 5 - 0 = -5

-5 = -5

Dr. Hoover, a pediatrician, has 3 annual checkups and 2 sick visits scheduled next Tuesday,
Jet001 [13]

Dr. Hoover allot his time on Tuesday for an annual checkup is 147 minutes and for a sick  visit is 42 minutes ​(Total 189 minutes)

On Wednesday appointment,  he allot his time for an annual checkup is 147 minutes and for a sick  visit is 21  minutes ​ (Total 168 minutes)

solution

Let us assume, minutes for annual checkup denoted as x and

minutes for sick visit denoted as y

The equation of Tuesday visit is       3x + 2y = 189 minutes ------ 1

The equation of Wednesday visit is    3x + 1y = 168 minutes ------ 2

by changing the signs of the equation 2  and  subtract it from the equation 1 we will get   1y = 21 minutes

to substitute y =1 in the equation 2 we get

3x + 2(21) = 189

3x + 42 = 189

3x = 189 - 42

3x = 147

x = 147 ÷ 3 = 49 minutes

then now we have substitute both x = 49 and y= 21 in equation ----- 2

we will prove that 3x + 2y = 189  = 3 (49) + 2(21) = 189 147+ 42 = 189 minutes

so the Tuesday appointment , the time allotted for an annual checkup is 147 minutes and for a sick  visit is 42 minutes ​(Total 189 minutes)

On Wednesday appointment,  the time allotted for an annual checkup is 147 minutes and for a sick  visit is 21  minutes ​ (Total 168 minutes)
