Simplifying the expression 8x +7 - 2x + y, by combining like terms is 6x + y + 7
<h3>How to simplify an expression?</h3>
The expression have to be simplified by combining the like terms.
Like terms are terms whose variables (and their exponents such as the 2 in y²) are the same.
Therefore,
8x +7 - 2x + y
The like terms are 8x and 2x . Therefore, lets combine it.
8x - 2x + y + 7
Therefore, the simplified expression is 6x + y + 7
