Answer:
-1.4
Step-by-step explanation:
substitute 10 and -3y
so it should look like -3y=10-5.8
then simplify so its -3y=4.2
divide both sides by -3 and you get y = 4.2/-3
multiply both the numerator and denominator by 10 and you get y= 42/-30
reduce the fraction to lowest terms by extracting and canceling out 6.
you end up with - 7/5 which simplifies to -1.4 so y = -1.4
