Solve 3x+2y from 3y-7x ( step by step)

$\huge \red{{\underline{\sf{Answer:-}}}}$

$\red{{{\tt{3y - 7x + 3x + 2y}}}} \: \: \:$

${{{\tt{ = 3y + 2y + 3x - 7x}}}} \: \: \: \:$

$\implies{{{\tt{ 5y - 4x}}}} \: \: \: \: {{{\bf{ Ans.}}}} \: \: \:$

⠀⠀⠀⠀⠀⠀

Explanation:-⠀⠀⠀⠀

• You can only add like terms.

- 3x + 4x - 5y - 7y

= 7x - 12y

You can only add x and x and only y and y.

Know More:-

Like Terms

• The terms having same variable factors.

• May differ in numerical coefficients.

= 3xy - 5xy + 2xy²

3xy and 5xy are like terms whereas 2xy² isn't because of the numerical coefficients.

⠀⠀⠀⠀⠀⠀⠀

Unlike Terms

• The terms having same variable factors.

=3x - 5xy

3x and 5xy are unlike terms as 3 just contains x but 5 contains x and z.
