Let first number is x
second number be y
one number is four less than a second number: x=y-4
Three times the first is 6 more than 6 times the second: 3x=6y+6
substitute x=y-4 in 3x=6y+6
3x =6y+6
3(y-4)=6y+6
3y-12=6y+6
3y-6y=6+12
-3y=18
y=-6
substitute y=-6 in x=y-4
x=-6-4=-10
so first number is -10
second number is -6
Answer:
(3, 8)
Step-by-step explanation:
Step 1: Substitute 3 for x. We get 10(3) - 6y = -18.
Then -6y = -18 - 30, or -6y = -48.
Step 2: Solve -6y = -48: Dividing both sides by -6, we get y = 8.
Step 3: Present the solution as (3, 8)
