Answer:
[tex](y {}^{2} - 4y) - ( {y}^{2} - 3y - 2y - 6) \\ - 4y - 3y - 2y - 6 \\ - 9y - 6 \: equals \: 10 \\ - 9y \: equals16 \\ y \: equals \: \frac{16}{ - 9} [/tex]
y = -(16/9)
y = 16
Step-by-step explanation:
y(y - 4) - (y - 2)(y - 3) = 10
Multiply/distribute.
(y² - 4y) - (y² - 5y + 6) = 10
Distribute negative symbol, rearrange.
y² - y² - 4y + 5y - 6 = 10
Combine like terms.
y - 6 = 10
Add 6 to both sides
