Answer 2

Given data:  -2x + 6y from 3x - 9y

To find: Subtraction of given expression

Solution:

• Subtraction is defined as the difference between two numbers.
• According to mathematic rule, Subtract two numbers we get a - b = c.
• In horizontal method the expression will be arranged in row or horizontal with negative sign.
• From the given expression we have $(3x - 9y)-(-2x + 6y)$.
• Now we need to add the second expression to first expression $3x - 9y+2x - 6y$.
• Combine the like teams together and do the arithmetic operation.$3x+2x-9y-6y$.
• Hence the subtraction of given expression is $5x-15y$ or $5(x-3y)$.
