Mathematics

Answer:

Since x= -3y + 6

Substitute this into equation 2

You now have equation 2 as

2(-3y+6) + 8y = -12

-6y + 12 + 8y = -12

8y - 6y = -12 -12

2y = -24

y= -12

x = -3(-12) + 6

x= 36 + 6

x= 42.

Answer:

x + 3y = 6

2x + 8y = -12

substracting first equation from the second will give us

x - 5y = -18

subtracting the first one from this will give us

-8y = -24

y = 3

x = -3

Solve 2x + 4 &gt; 16<br><br> A. x &gt; 10<br> B. x &lt; 6<br> C. x &lt; 10<br> D. x &gt; 6
Salsk061 [2.6K]

Hey there! :)

2x + 4 > 16

We're simply just trying to get x onto it's own side, so let's get rid of any numbers on the same side of it.

We can start out by subtracting both sides by 4.

2x + 4 - 4 > 16 - 4

Simplify.

2x > 12

Then, divide both sides by 2.

2x ÷ 2 > 12 ÷ 2

Simplify.

x > 6

Therefore, our answer is D. x > 6

~Hope I helped!~

Solve for x<br> Please.
Sonja [21]

Answer:

B

Step-by-step explanation:

Since the triangle is right use the tangent ratio to find x

tan64° = \frac{opposite}{adjacent} = \frac{x}{11}

Multiply both sides by 11

x = 11 × tan64° = 22.55 → B

X/(x-2) + (x-1)/(x+1) = -1 <br><br> How to solve?
kirill115 [55]
Multiply entire equation by (x-2)(x+1) to get rid of the denominators That would lead to X(x+1)+(x-1)(x-2)=-1(x-2)(x+1)
Finally, using distributive property and foil, you would get x^2+x+x^2-3x+2=(-x^2+x+2).2x^2-2x+2=-x^2+x+23x^2-3x=0
3x(x-1)x=0 and x=1
