Solve the system of equations.<br><br><br> ​ <br><br> −5y−10x=45<br> −3y+10x=−5<br> ​
Fynjy0 [20]
(-2,-5)
The first goal with equations like these is to get one of the variables to go away. You can do that by adding/subtracting one equation from the other. Then you solve for the one variable. Then you plug that answer into one of the original equations and solve.

Prove that the value of the expression does not depend on the variable x:
Leviafan [203]

Answer:

See below

Step-by-step explanation:

If an expression is not dependent on x, it simplified form must not contain x. To show that this is the case for (a) and (b) we need to simplify them and assess:

(a)

(x-5)(x+8)-(x+4)(x-1)=\\=x^2-5x+8x-40-x^2-4x+x+4=-36

Indeed, does not depend on x!

And (b)

x^4-(x^2-1)(x^2+1)=x^4-x^4+x^2-x^2+1=1

Again, does not depend on x.

(5 + x) / 6 = -1....multiply both sides by 6, cancelling out the 6 on the left side
5 + x = -1 * 6
5 + x = -6
x = -6 - 5
x = -11
