The solution is: x= 7 and y = 2
Step-by-step explanation:
Given equations are:
Putting x = 3y+1 in equation 2 from equation 1
Subtracting 1 from both sides
Dividing both sides by 7
Putting y=2 in equation 1
Hence,
The solution is: x= 7 and y = 2

The 5 ft. and 3 in. total to 63 in. So, you take away 5 in. from 63 in. and your total would be 58 in. (4 ft. 10 in.)
Answer: 58 inches or 4 feet 10 inches

even when you don't see it,
God's working : )
Let 2x – y = 3 ——— equation 1
Let x + 5y = 14 ——— equation 2
Making x the subject in eqn 1, = x = y + 3 / 2 ——— eqn 3
• Put eqn 3 in eqn 2
(y + 3 / 2) + 5y = 14
6y = 14 – 3/2
6y = 25/2
y = 25/12
• put y = 25/12 in eqn 3
x = (25/12 + 3/2)
x = 43/12
I think the answer is B.
6(-3)=-18, and y=2
so 6x-y=-18-2=-20
