2(5b-7), you can input b as 3y
2(5(3y)-7) —> 2(15y-7) —> 30y -14 
—> 30y = 14 —> y = 14/30 —> y = 4.6667

Answer:
simple just follow me and mark it brainliest
Step-by-step explanation:
LET THE THREE CONSECUTIVE EVEN INTEGERS BE
(x+2) ,(x+4) ,(x+6)
then
according to the question
4(x+2) – (x+6) = 2(x+4) + 6
4x + 8 – x – 6= 2x + 8+6
3x +2 = 2x + 14
3x – 2x= 14 –2
x= 12
the numbers are
