You add -125 by its opposite which is 125 so 2x(-125+125)=400+125
2x=525
You then divide both sides by 2 and you get
X=262.5

2x-125=400

Add 125 to both sides

2x-125+125=400+125

2x=525

Divide both sides by 2

2x/2=525/2

x= 262.5


Let me check if my work is good

2(262.5)-125=400

525-125=400

400=400


So yes , my answer is good and I hope its help !

Solve the system using elimination. 3x + 3y = –9 3x – 3y = 21
scoundrel [369]

Answer:

y=-5,x=2

Step-by-step explanation:

3x+3y=-9________________eqn 1

3x-3y=21________________eqn 2

using elimination method

3x+3y=-9

-

3x-3y=21

subtract equation 2 from equation 1

0+6y=-30

6y=-30

y=-30/6

y=-5

substitute the value of y in equation 1

3x+3y=-9

3x+3(-5)=-9

3x-15=-9

3x=-9+15

3x=6

x=6/3

x=2
