Which step was the first error made? -3\left(2x-3\right)=33−3(2x−3)=33 -6x+6=33−6x+6=33 step 1 -6x=27−6x=27 step 2 \frac{\left(-

Afina-wow [57]

Given:

The equation is

$-3(2x-3)=33$

The incorrect solution steps are given.

To find:

The first error.

Solution:

We have,

$-3(2x-3)=33$

Using distributive property, we get

$-3(2x)-3(-3)=33$

$-6x+9=33$

The given step 1 is $-6x+6=33$ , which is not correct.

Therefore, there is first error in step 1 because the distribution property is not used properly.

Hence, the correct option is D.

Question: What is the solution to the equation $\bold{x\cdot \:2=9x+6}$

Answer: $\boxed{\bold{x=-\frac{6}{7}}}$

Explanation: $\downarrow{\downarrow{\downarrow{}}}$

[ Step One] Subtract 9x From Both Sides Of Equation

$\bold{x\cdot \:2-9x=9x+6-9x}$

[ Step Two ] Simplify Equation

$\bold{-7x=6}$

[ Step Three ] Divide Both Sides By -7

$\bold{\frac{-7x}{-7}=\frac{6}{-7}}$

[ Step Four ] Simplify

$\bold{x=-\frac{6}{7}}$

$\bold{\rightarrow{}Rhythm \ Bot\leftarrow{}}$

Five times the sum of a number and 7 equals 3

miv72 [106K]

The answer or number that you are looking for is -6.4. You can get this by dividing 3 by 5 which is equal to 0.6. Next you would subtract 7 to reverse the act of having added it. This will give you -6.4 which is what you are looking for.
