13x + 7 = 5x - 20
13x - 5x = -20 - 7
8x = -27
x = (-27 / 8)
x = -(27/8)

Solve 3(x - 4) = 11x

Ivanshal [37]

Answer:

$x = \frac{-3}{2}$

Step-by-step explanation:

3(x - 4) = 11x

Expand the brackets:

3x - 12 = 11x

Subtract 3x from both sides to isolate the -12:

3x - 12 = 11x

3x - 3x - 12 = 11x - 3x

-12 = 8x

8x = -12

Divide both sides by 8:

$\\\frac{8x}{8} = \frac{-12}{8}\\x = \frac{-12}{8}\\$

Simplify fraction:

$x = \frac{-12}{8}$

$x = \frac{-12 \div 4}{8 \div 4}\\x = \frac{-3}{2}$

Hope this helps!

Directions: Write each equation in slope intercept form (y = mx + b)

Gnesinka [82]

Answer:

Below.

I Hope it helps :)

Step-by-step explanation:

Slope intercept form :

y=mx+b

$2x + y = 1$

Slope intercept form :

$y = - 2x + 1$

Equation :

$x - 2y = 8$

Slope intercept form :

$- 2y = - x + 8$

$y = \frac{1}{2} x - 4$

$3x + 2y = 4$

Slope intercept form :

$2y = - 3x + 4 \\$

Divide through by 2

$y = - \frac{3}{2} x + 2$

Equation :

$x + 2y = - 4$

Slope intercept form :

$2y = - x - 4$

Divide through by 2

$y = - \frac{1}{2} x - 2$

$4x + y = 1$

Slope intercept form =

$y = - 4x + 1$

Equation :

$x + y = - 2$

Slope intercept form :

$y = - x - 2$

Solve using the substitution method

makkiz [27]

14-4x=2y divide 2 to both sides
VVVVV
7-2x=y you will need this on the next step
-----------------------------------------------------
y+2x=7
y=7-2x
(7-2x)+2x=7 -------> 7-2x+2x=7
7=7
The answer is C.
