Solve for x.<br> x-8=-20

NeX [460]

Answer:

Step-by-step explanation:

To solve:

x - 8 = -20

Simply add +8 to both sides of the equation.

It becomes :

x - 8 +8 = -20 + 8

Note that, -8 + 8 will cancel out, and results to zero.

Therefore the equation becomes :

x = -20 + 8

x = -12.

Hope this helped!

Factor, show all steps. x2 – 16x + 64 = 0

lora16 [44]

$x^2-16x+64=0$

Method 1.

Use $(a-b)^2=a^2-2ab+b^2$

$x^2-2\cdot x\cdot8+8^2=0\\\\(x-8)^2=0\\\\(x-8)(x-8)=0$

Method 2.

$x^2-8x-8x+64=0\\\\x(x-8)-8(x-8)=0\\\\(x-8)(x-8)=0$

The solution to this equation is the number 8

2x+2y=-2<br> 3x-2y=12<br><br> I do not understand this math and need help with this math equation.

Step-by-step explanation:

You have two equations and two "unknowns" x and y.

This is an easy one. Add the two equations together, which will eliminate the y terms so you can solve for x:

2x+2y = -2

3x-2y = 12

---------------

5x = 10, so x = 2.

Now plug the 2 back into one of the equations and solve it for y.

2(2)+2y = -2

4+2y = -2

2y = -6

y = -3
