Step-by-step explanation:

1)Let's solve for x.

−10x+8y=102x+2y

Step 1: Add -102x to both sides.

−10x+8y+−102x=102x+2y+−102x

−112x+8y=2y

Step 2: Add -8y to both sides.

−112x+8y+−8y=2y+−8y

−112x=−6y

Step 3: Divide both sides by -112.

2)Let's solve for x.

8x−6y=−12−3x+12y

Step 1: Add 3x to both sides.

8x−6y+3x=−3x+12y−12+3x

11x−6y=12y−12

Step 2: Add 6y to both sides.

11x−6y+6y=12y−12+6y

11x=18y−12

Step 3: Divide both sides by 11.

3)Let's solve for x.

5x+4y=−252x+3y

Step 1: Add 252x to both sides.

5x+4y+252x=−252x+3y+252x

257x+4y=3y

Step 2: Add -4y to both sides.

257x+4y+−4y=3y+−4y

257x=−y

Step 3: Divide both sides by 257.

answer:  

step-by-step explanation:

odd numbers are only divisible by 1 and itself.

even numbers are divisible by more than 1 and itself.

for example 6 is even because it is divisible by more than 1 and its self. 1 x 6= 6 ; 2 x 3= 6

and 7 is odd because only 7 x 1 equals seveb
