Answer:
Y=2
Step-by-step explanation:
<em>Simplifying
</em>
4y + 1 = 9
<em>Reorder the terms:
</em>
1 + 4y = 9
<em>Solving
</em>
1 + 4y = 9
<em>Solving for variable 'y'.
</em>
<em>Move all terms containing y to the left, all other terms to the right.
</em>
<em>Add '-1' to each side of the equation.
</em>
1 + -1 + 4y = 9 + -1
<em>Combine like terms: 1 + -1 = 0
</em>
0 + 4y = 9 + -1
4y = 9 + -1
<em>Combine like terms: 9 + -1 = 8
</em>
4y = 8
<em>Divide each side by '4'.
</em>
y = 2
