-7.7=-1.3+y/4 can someone help me solve this equation?

Solve for y:
-7.7 = y/4-1.3

Put each term in y/4-1.3 over the common denominator 4: y/4-1.3  =  y/4-(5.2)/4:
-7.7 = y/4-(5.2)/4

y/4-(5.2)/4 = (y-5.2)/4:
-7.7 = (y-5.2)/4

-7.7 = (y-5.2)/4 is equivalent to (y-5.2)/4 = -7.7:
(y-5.2)/4 = -7.7

Multiply both sides of (y-5.2)/4 = -7.7 by 4:
(4 (y-5.2))/4 = -7.7×4

(4 (y-5.2))/4 = 4/4×(y-5.2) = y-5.2:
y-5.2 = -7.7×4

4 (-7.7)  =  -30.8:
Answer: | 
| y-5.2 = -30.8          y=-128/5

-7.7=-1.3+y/4    multiply each term by 4

-30.8  = -5.2 + y     add 5.2 to both sides

-25.6  = y
