Subtracting a negative number is the same as adding

5-(-5) = 10
5+5 = 10

For example, 1-1=0. If you use subtraction, you can think of it as 1+(-1)

Hep asappppppppppppp

Answer:

(6 , -1)

Step-by-step explanation:

2x+ y = 11 ----------------(I)

y = 11 - 2x --------------------(II)

$\frac{1}{2}x - 5y = 8$

Multiply the whole equation by 2

$2*\frac{1}{2}x -2*5y = 2*8$

x - 10y = 16 --------------------(III)

Substitute y = 11- 2x in equation (III)

x - 10(11 - 2x) = 16

x - 110 + 20x = 16

21x - 110 = 16

21x = 16 +110

21x = 126

x = 126/21

x = 6

Plugin x = 6 in equation (II)

y = 11 - 2*6

y = 11 - 12

y = -1

vlada-n [284]

Answer:

300-20x<100

Step-by-step explanation:

More than, is like greater than, making it a greater than sign,

$100 is the number that is being compared to the other two, so it goes on the other side

$300 is the inital price, so it has no variable

Last, the $20 represents the cost per shirt giving it an unknown variable

I hope this helps u

5x-3y when x=7 and y=-8

I am Lyosha [343]

5 (7) - 3 (-8)

35 - -24

Because two negatives equal a positive the subtraction sign will change into an addition sign.

35+24

So your answer will be 59.

Hope this helped :)
