What is the answer (algebra) <br> -(4x + 3x) = 10x - 5
MariettaO [177]

Step-by-step explanation:

-(4x + 3x) = 10x - 5

We would have to multiply the -1 by the 4x and the 3x which is in the bracket.

Though there is no 1 behind the bracket but, behind any bracket there is 1 there even though it's ignored.

So when we multiply -1 by 4x we are going to get;

-4x

And when we multiply -1 by 3x It's going to be;

-3x

We have -3 and -4 because whenever we multiply any positive and negative number the product is negative.

So;

-4x - 3x = 10x - 5

So now, we group like terms;

- 4x - 3x - 10x = -5

So now that we have grouped, we have to add the negative numbers even though there is no addition sign there we would have to add

-17x = -5

So now we divide both sides by;

-17

Which is going to be;

x=

\frac{5}{17}

A student says that if 5x2 = 20, then x must be
lutik1710 [3]

Answer:

I agree with the student's answer. "x" cannot be -2 because then it would make -20 which is not equal to 20:

5(-2)(2) = ?

-10 x 2 = ?

? = -20

-20 ≠ 20

Step-by-step explanation:

Justificaiton:

5(x)(2) = 20

10(x) = 20

10/10(x) = 20/10

x = 2

Second Justification:

5(x)(2) = 20

5/5(x)(2) = 20/5

2x = 4

2x/2 = 4/2

x = 2
