Multiply by the reciprocal by 3 and divide the common denominator by 14
Problem 12)
You are correct. You solve the system
x+1 = 3y
3x-4 = 5y+1
for x and y to find that x = 5 and y = 2
As a check
x+1 = 3y
5+1 = 3*2
6 = 6 ... true equation
and
3x-4 = 5y+1
3*5-4 = 5*2+1
11 = 11 ... true equation
Both equations are true when (x,y) = (5,2) so the answer is confirmed

Answer:
One answer is x = 1, y = -1, and z = 2.
The answer is 105. If you look at the pattern, sequence 2 goes up in 15. 75 + 15 + 15 = 105.
Answer:
3
Step-by-step explanation:
2x=6 hence the number is 3
