-2a-4>-8 please help
grandymaker [24]
Hey there!

Firstly, we have to “add” the number “4” on each of your sides

Like: -2a -4 + 4> -8 +4
Cancel: -4 + 4 because it will give you “0”
Keep: -8+4 because it gives you “-4” and we have paid it off with -2a

Like: -2a>-4

Divide each of the sides by “-2”

Like: -2a/2 > -4/-2

Cancel: -2a/2 because it gives us “1”

Keep: -4/-2 because that’ll give us the answer on the left side of the inequality

So, a < 2 would be your answer

Good luck on your assignment and enjoy your day

Solve 4(-4x- 3)&gt; 36
wariber [46]

Answer:

x=3

Step-by-step explanation:

Simplifying

4(4x + -3) = 36

Reorder the terms:

4(-3 + 4x) = 36

(-3 * 4 + 4x * 4) = 36

(-12 + 16x) = 36

Solving

-12 + 16x = 36

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '12' to each side of the equation.

-12 + 12 + 16x = 36 + 12

Combine like terms: -12 + 12 = 0

0 + 16x = 36 + 12

16x = 36 + 12

Combine like terms: 36 + 12 = 48

16x = 48

Divide each side by '16'.

x = 3

Simplifying

x = 3
