-2(6-x)= 3x, the solution is  find the value of x,  you must apply distributive property, tho the first term,  -12+2x= 3x⇒ 3x-2x= -12⇒ x = -12, the  answer correct is option D

The answer is "D" because after you distribute the -2 you must move the -2 to the other side and solve as normal

Given the two points what is the slope of the line?<br> (4,2) (10.4)
zlopas [31]

m = \frac{y2-y1}{x2-x1}\\ m=\frac{4-2}{10-4} \\m = \frac{2}{6} \\\\m=\frac{1}{3}

Therefore, the slope of the line is 1/3. In case if you want the equation too.

y=mx+b\\y=\frac{1}{3}x+b\\ 2=\frac{1}{3}(4)+b\\ 2=\frac{4}{3}+b\\ b=-\frac{4}{3}+2\\ b=-\frac{4}{3} +\frac{6}{3}\\ b=\frac{2}{3}

Therefore, the equation is y=1/3x+2/3

Solve for x: 3-x = 3(6x-9). Describe the process used to solve the equation and show each step.
FromTheMoon [43]

Answer:

x=1.578

Step-by-step explanation:

Given equation is 3-x = 3(6x-9)

We need to find the value of x

3-x = 3(6x-9)

Distribute 3 in the right-hand side  

3-x=18x-27

Add both sides x

3-x+x=18x+x-27\\3=19x-27

Now, add both sides 27

3+27=19x-27+27\\30=19x

Divide both sides by 19

\frac{30}{19}=\frac{19x}{19}\\x=1.578

So, x=1.578
