Answer:

C. The equation has no solution

Step-by-step explanation:

We can tell by looking at the equation that number of possible solutions is one because the highest power is 1. However we do not know what the solution is exactly, so let's solve it.

First let us start by distributing the 2 to the (4x + 10) which gives us 8x +20 = 8x + 12

Now we can subtract 20 from both sides to give us 8x = 8x - 8

Now we can subtract 8x from both sides to give us 0 = -8

Since the x's have cancelled out, and 0 ≠ -8 there are no solutions for x that make this equation true

WORTH 60 POINTS! PLZ HELP! BRAINLIEST OPPORTUNITY!
makkiz [27]

Answer:

x = 10

Step-by-step explanation:

2) -3x + 17 = -x - 3

4) 20 = 2x

1) -3x + 12 + 5 = -x -3

5) 10 = x

3) 17 = 2x - 3

<u>-3(x - 4) + 5 = -x - 3</u>

<u>-3x + 12 + 5 = -x - 3</u>

<u>-3x + 17 = -x -3</u>

<em>+3x          +3x</em>

<u>17 = 2x - 3</u>

<em>+3        + 3</em>

<u>20 = 2x</u>

<u>10 = x</u>

<u />

I hope that this helps! :)

How many solutions does this equation have? -4(5-3x)=12x+20​
UNO [17]

Answer:  The number of solutions to the given equation is zero.

Step-by-step explanation:  We are given to find the number of solutions to the following equation :

-4(5-3x)=12x+20~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

To find the number of solutions, we must solve the given equation.

The solution of equation (i) is as follows :

-4(5-3x)=12x+20\\\\\Rightarrow 5-3x=\dfrac{12x+20}{-4}\\\\\Rightarrow 5-3x=-3x-5\\\\\Rightarrow -3x+3x=-5-5\\\\\Rightarrow 0=-10, which can never be possible.

So, the given equation has no solution.

Thus, the number of solutions to the given equation is zero.
