Answer:

A. 1 [tex]\frac{7}{8}[/tex]

Step-by-step explanation:

2/3y - 1 = 1/4

Add 1 to both sides.

2/3y = 5/4

Divided by 2/3 on both sides.

y = 15/8 or 1 [tex]\frac{7}{8}[/tex]

So, the answer is A. 1 [tex]\frac{7}{8}[/tex]
2/3y-1=1/4
Multiply both sides of the equation by the common denominator
2 x 12y/3y - 12y =12y/4
Reduce the fraction
8 - 12y = 3y
Rearrange the variables to the left side of the equation
-12y - 3y = -8
Combine like terms
-15y = -8
Divide both sides of the equation by the coefficient of the variable
y=-8/-15
Y=8/15
