Answer:

y=5/4=0.8

Step-by-step explanation:

(4×2y−8)−13y=−12

Multiply 4 and 2 to get 8.

8y−8−13y=−12

Combine 8y and −13y to get −5y.

−5y−8=−12

Add 8 to both sides.

−5y=−12+8

Add −12 and 8 to get −4.

−5y=−4

Divide both sides by −5.

y=−5−4

Fraction −5/−4 can be simplified to 5/4 by removing the negative sign from both the numerator and the denominator.

y=5/4
