Half of a number decreased by 8 is 3

AURORKA [14]3 years ago

With the Brainly help you've gotten in the last 15 minutes or so,
you should be able to do this one now.

The mystery number . . . . . . .      M
Half of it . . . . . . . . . . . . . . . .  1/2 M
Half of it decreased by  8 . . .  1/2 M - 8

You said that's  3 .
So the equation you have to solve is

                                      1/2 M - 8  =  3

Add  8  to each side:      1/2 M       =  11

Multiply each side by  2 :      M       =  22

This is easier than the last one we ( I ) did.

If A + B = 2X -2 and A -B equals 4X -8, find A and B
Keith_Richards [23]
A=3X-3
B=-X+3
If A+B=2X-2, then using equalivant exchange A=2X-2-B and
B=2X-2-A
If A-B=4X-8, then A=4X-8+B and -B=4X-8-A(or B=-4X+8+A)
Since A equals both 2x-2-B and 4X-8+B we can add both equations to equal 2A=6X-6 now we devide that by 2 to get
A=3X-3
Do the exact same for B, so b equals both 2X-2-A and -4X+8+A
We can add them both to get 2B=-2X+6 and decide that by 2 to get B=-X+3
