Answer:
Y = -4.5x
Step-by-step explanation:
First evaluate: -16x to the second power = -256x
Then add like terms: -256x + 238x = -18x
Then divide both sides by -18: -18x divided by -18/ 81 divided by -18
Which leaves you with y = -4.5x
Simplifying the expression 8x +7 - 2x + y, by combining like terms is 6x + y + 7

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
