x + 7 = 2(3x - 4) Remove the brackets

x + 7 = 2*3x - 4*2

x + 7 = 6x - 8 Subtract 7 from both sides.

x + 7 - 7 = 6x - 8 - 7

x = 6x - 15 Subtract 6x from both sides

x - 6x = - 15

-5x = - 15 Divide by -5

-5x/-5 = -15/-5

x = 3

Write the equation of the line shown (3,6) (3,-4)

lozanna [386]

Answer:

The equation of line is given as $x=3$

Step-by-step explanation:

Point on the line given :

$(3,6),(3,-4)$

We can find the slope of the line first from the given points.

Slope $(m)=\frac{y_2-y_1}{x_2-x_1} = \frac{-4-6}{3-3}=\frac{-10}{0}=$ = Undefined.

The slope of the line is undefined which means that the line is parallel to y-axis.

From the points known to us we can tell that the line passes through $x=3$

∴ The equation of line is given as $x=3$

Answer:

$\large\boxed{-3(2+4k)+7(2k-1)=2k-13}$

Step-by-step explanation:

$-3(2+4k)+7(2k-1)\qquad\text{use the distributive property}\ a(b+c)=ab+ac\\\\=(-3)(2)+(-3)(4k)+(7)(2k)+(7)(-1)\\\\=-6-12k+14k-7\qquad\text{combine like terms}\\\\=(-12k+14k)+(-6-7)\\\\=2k-13$
