David’s Equation Amanda’s Equation
y = 12,350 – (240x) y = 12,350 + (240x)
Which person has the correct equation to model this linear relationship?
Amanda’s equation is correct, because their spending will be multiplied by the number of months and then added to their savings.
Amanda’s equation is incorrect, because their spending will increase the amount of their savings.
David’s equation is correct, because their spending will be multiplied by the number of months and then subtracted from their savings.
David’s equation is incorrect, because their spending should be a fixed amount and should not be multiplied
Solve x
Substitute -y+6 for x in 3x-4y=-31
3x-4y=-31
3(-y+6)-4y=-31
Simplify both sides of the equation
-7y + 18 = -31
Add -18 to both sides
-7y+18-18=-31-18
7y= -49
Divide both sides by -7
7y/-7= -49/-7
y= 7
Substitute 7 for y in x = -y+6
x= -y+6
x= -7+6
Simplify both sides of the equation
x= -1
Answer : x= -1 and y = 7
I hope that's help and have a great night !
