Answer:
(- 5, 3 )
Step-by-step explanation:
Given the 2 equations
y = - 8x - 37 → (1)
x + 3y = 4 → (2)
Substitute y = - 8x - 37 into (2)
x + 3(- 8x - 37) = 4 ← distribute and simplify left side
x - 24x - 111 = 4
- 23x - 111 = 4 ( add 111 to both sides )
- 23x = 115 ( divide both sides by - 23 )
x = - 5
Substitute x = - 5 into (1) for corresponding value of y
y = - 8(- 5) - 37 = 40 - 37 = 3
Solution is (- 5, 3 )
Answer:
something
Step-by-step explanation:
Answer:
x = 9
y = 6
Step-by-step explanation:
3x+6i=27+yi
The real components have to be equal and the imaginary components have to be equal
3x = 27
divide by 3
3x/3 = 27/3
x=9
6i = yi
Divide by i
6 = y
Let x = the larger number
Let y = the smaller number
x + y = 93
x - y = 19 Add the two equations together.
2x = 112 Divide both sides of the equation by 2.
x = 56
56 + y = 93 Subtract 56 from both sides of the equations.
y = 37
I agree. There can't ever be 2 equal signs in A math problem
