Answer:</h3>
(5/7, 12/7) <- I think you meant to type that. Its the first one
<h3>
Step-by-step explanation:</h3>
Step 1: Substitute y=x+1 in for y in 5x + 2y = 7
5x + 2(x+1) = 7
Step 2: Solve it
5x + 2x + 2 = 7
7x + 2 = 7
- 2 - 2
7x = 5
--- ---
7 7
x = 5/7
Step 3; Plug x into y=x+1
y = 5/7 + 1
y = 12/7
When dividing a number by itself the outcome will always be 1
Answer:
y = 3/2
Step-by-step explanation:
5(2y - 1) - 2(3y) = 1
First we use distributive property:
10y - 5 - 6y = 1
because 5 × 2y = 10y
and -2 × 3y = -6y
Now we combine the like terms:
4y -5 = 1
because 10y - 6y = 4y
Now we have to send the -5 to the other side. (when we send it to the other side it becomes positive because right now it is negative)
4y = 1 + 5
Again we combine the like terms:
4y = 6
(because 5 + 1 = 6)
Now we have to send the 4 to the other side because we need to get the y value. (when we send it to the other sidr it will be divided)
y = 6/4
and we simplify:
y = 3/2
And we cannot simplify or do anything else. So that is the answer.
Hope that helped!
