I need hlep its do to day

Answer:

x = -6/5

Step-by-step explanation:

distribute -4 on the left side of the equation first, then distribute 2 on the right side of the equation to get:

16x - 4 - 4x = 2x - 14 - 2

combine 'like terms':

12x - 4 = 2x - 16

subtract '2x' from each side to get:

10x - 4 = -16

add 4 to each side to get:

10x = -12

x = -12/10 or x = -6/5

Someone PLEASE help me!!!!!<br> Evaluate -/3/

Veseljchak [2.6K]

if / means absolute value, then the answer is -3. The absolute value of 3 is 3, then you take the negative value of it, which is -3.

Btw, the absolute sign is ||, not //.

How do i do this pls help me

Delvig [45]

Answer:

$y = \frac{1}{7} x + 7$

Step-by-step explanation:

x-7y = -49

i) move x to the right-hand side and change its sign

-7y = -49-x

ii) change the signs on both sides of the equation

7y = 49+x

iii) divide both sides of the equation by 7

$\frac{7y}{7} = \frac{49}{7} + \frac{x}{7}$

$y = 7 + \frac{1}{7} x$

iv) use the commutative property to reorder the terms

* commutative property: a+b = b+a

$y = \frac{1}{7} x + 7$
