How many solutions does x + 2x + 7 = 3x - 7

Mathematics
1 answer:
Alex17521 [72]3 years ago
3 0

Answer:

No solutions! :)

Step-by-step explanation:

To find the number of solutions in a problem we must solve it.

x+2x+7=3x-7

Firstly, combine common terms:

3x+7=3x-7

We can subtract 3x from both sides:

7=-7

The solution is 7=-7, which is no solution.

When a number is equal to a number in a solution, it has no solutions!

1/4(z +3z)+ 7=−z + 1 please help with this ive been stuck
erastovalidia [21]

Answer:

<em><u>z = -3</u></em>

Step-by-step explanation:

<u>Step 1: Simplify both sides of the equation. </u>

z+7=−z+1

<u>Step 2: Add z to both sides. </u>

z+7+z=−z+1+z

2z+7=1

<u>Step 3: Subtract 7 from both sides. </u>

2z+7−7=1−7

2z=−6

<u>Step 4: Divide both sides by 2. </u>

<u>2z</u>   =  <u>−6 </u>

2      2

z=−3

Solve 2(x-3)&gt;-3(-3+x)<br><br> (Picture added, multiple choice)
Rudiy27

Answer:

<u>Answer</u><u>:</u><u> </u><u>D</u>

Step-by-step explanation:

2(x - 3) \geqslant  - 3( - 3 + x)

open the brackets [ distributive property ]

2x - 6 \geqslant 9 - 3x

collect like terms:

2x + 3x \geqslant 9 + 6 \\ 5x  \geqslant 15

divide either sides by 5:

\frac{5x}{5}  \geqslant  \frac{15}{5}  \\  \\ { \underline{ \bf{ \:  \: x \geqslant 3 \:  \: }}}
