Answer:
y = 2
Step-by-step explanation:
Given
(y + 7) = 3(y - 1)
Multiply both sides by 3 to clear the fraction
y + 7 = 9(y - 1) ← distribute
y + 7 = 9y - 9 ( subtract 9y from both sides )
- 8y + 7 = - 9 ( subtract 7 from both sides )
- 8y = - 16 ( divide both sides by - 8 )
y = 2
1/8; say you have one whole pie, cut into fourths, than take one fourth, or one quarter, and cut that in half, it's the same as if you cut the whole pie in half than cut those halfs in half, making quaters, than cutting them in half, making a pie thats cut in eights, each slice is 1/8, one eight
Answer:
2x + 3
Step-by-step explanation:

= x² + 7x + 1 - x² - 5x + 2 ← collect like terms
= 2x + 3
