Solve the following inequalities.

Airida [17]

$-4x-2$

Add 2 to both sides:

$-4x$

Divide both sides by -4 (this is negative, so we have to swap the inequality sign):

$x>\dfrac{5}{2}$

$2(y-4)\leq 10-y$

Expand the left hand side:

$2y-8\leq 10-y$

Add 8 and y to both sides:

$3y\leq 18$

Divide both sides by 3

$y \leq 6$

3-4

Nothing different from 1 and 2, apply the same logic (expand sides, gather constant and non-constant terms together, solve for the variable) and you will solve them

-3(y-50)=24 Plz help -sob-

Leni [432]

Answer: y=42

Step-by-step explanation:

division property of equality is dividing both sides of an equation by the same non-zero number does not change the equation.

divide by -3 both sides of an equation.

-3(y-50)/-3=24/-3

simplify.

y-50=-8

add 50 both sides of an equation.

y-50+50=-8+50

simplify.

-8+50=42

50-8=42

42+8=50

y=42

Hope this helps!

Thanks!

Have a great day!

What value of x makes the vertical parts of the letter N parallel? picture provided

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

$2x + 9 = 5x$

$5x = 2x + 9$

Subtract sides 2x

$- 2x + 5x = - 2x + 2x + 9$

$3x = 9$

Divide sides by 3

$\frac{3x}{3} = \frac{9}{3} \\$

$x = 3$

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

CHECK :

$2x + 9 = 5x$

$2(3) + 9 = 5(3)$

$6 + 9 = 15$

$15 = 15$

So the value is correct.
