How do you solve for
Y=-9x-4
Y=5x+10
?
1 answer:
Answer: {y,x} = {-1,1}
Step-by-step explanation:
Solve equation for the variable y
y = -5x + 4
this in for variable y in equation
(-5x+4) - 9x = -10
- 14x = -14
Solve equation or the variable x
14x = 14
x = 1
By now we know this much :
y = -5x+4
x = 1
Use the x value to solve for y
y = -5(1)+4 = -1
