Answer:

(-1, 7)

Step-by-step explanation:

Step 1 - Make the two equations equal the same:

3x + y = 4

2x + y = 5

Add 1 to the first equation:

3x + y + 1 = 5

2x + y = 5

3x + y + 1 = 2x + y

Step 2 - Subtract 2x from both sides to isolate y:

3x + y + 1 = 2x + y

3x - 2x + y + 1 = 2x - 2x + y

x + y + 1 = y

Step 3 - Subtract y from both sides:

x + y + 1 = y

x + y - y + 1 = y - y

x + 1 = 0

x = -1

Step 4 - Plug known variable back into the first equation:

3x + y = 4

3(-1) + y = 4

-3 + y = 4

Step 5 - Add 3 to both sides to isolate the y:

-3 + y = 4

-3 + 3 + y = 4 + 3

y = 7

Meaning the two coordinates  are:

x = -1

y = 7

Or:

(-1, 7)

Hope this helps!

6 sweets cost 42p altogether how much do 8 sweets cost
Eddi Din [679]
The best thing to do is to find the cost of one sweet, and to do this, divide 42 by 7.
42/7= 6
Therefore, one sweet costs 6p.
To find the cost of 8 sweets, you've got to multiply 6 by 8, and this gives you 54p.
Therefore, 8 sweets cost 54p
This is basically just finding unit rate and multiplying.
