Answer:

a = 15

Step-by-step explanation:

Given

3a + b = 54 ← substitute b = 9

3a + 9 = 54 ( subtract 9 from both sides )

3a = 45 ( divide both sides by 3 )

a = 15

3a+b=54, b=9

3a +9 =54

3a= 54-9=45

a= 45÷3=15

Four times the greater of two consecutive integers is 18 more than three times the lesser integer. What are the integers?

maw [93]

This is how I would solve it:

1st # = x 4(x+1)=3x+18
2nd # = x+1 4x+4=3x+18
4x=3x+14
x=14

To check: 15x4=60; 60-42=18. <u>1st # = 14; 2nd # = 15.</u>
