Answer:
x = 2, y = - 1
Step-by-step explanation:
Given the 2 equations
y = - 7x + 13 → (1)
y = - 1 → (2)
Substitute y = - 7x + 13 into (2)
- 7x + 13 = - 1 ( subtract 13 from both sides )
- 7x = - 14 ( divide both sides by - 7 )
x = 2
y = - 1 is already given in (2)
Then x = 2, y = - 1
It showed that: y = -1
So the equation will be: -1 = -7x + 13
Now we solve from here, start by subtracting 13 on both sides:
-14 = -7x
Divide -7 on both sides:
2 = x
So the equation will be: -1 = -7x + 13
Now we solve from here, start by subtracting 13 on both sides:
-14 = -7x
Divide -7 on both sides:
2 = x
