Answer:

Multiply the 2nd row by 3.

Step-by-step explanation:

2x + 3y = 18

21x - 3y = 30

Now, if we combine these two equations, y will disappear and we'll have:

23x = 48, so that

x = 48/23.

Anthony's weight is nine pounds more than twice his brothers weight. Anthony's weighs 59 pounds. how much does his brother weigh

ahrayia [7]

A = Anthony's weight
B = Anthony's brother's weight

A = 2B + 9 Plug in Anthony's weight
59 = 2B + 9 Subtract 9 from both sides
50 = 2B DIvide both sides by B
25 = B Switch the sides to make it easier to read
B = 25

Anthony's brother weighs 25 pounds.
