Solving Linear Equations
2x + 6 =0
x = -3
(x - 5)(x + 3) = 0
x = 5, and x = -3
What is the value of the y-coordinate of the solution to the system of equations x + 2y = 9 and x - y = 3?
y = 2
The second name of out principal?
Peguero
2x - 18 = -3x + 27
x = 9
x^2 - 9x + 18 = 0
x = 6 or x =3
The name of the math teacher of 4ºA
María
7x + 42 = -3x - 28
x = -7
Solve 3x^2 = 48
x = 4 and x = -4
The equations 5x + 2y = 48 and 3x + 2y = 32 represent the money collected from school concert ticket sales during two class periods (in euros). If x represents the cost for each adult ticket and y represents the cost for each student ticket, what is the cost for each adult ticket?
The cost is 8€
Tricia's nationality?
No idea. She has to say it.
2x/3 + x/6 = 5
x = 6
2(x + 2)^2 - 4 = 28
x = -6 and x = 2
3x^2 + 12xy - 12y^2
3(x + 2y)(x + 2y)
The equations 6x + 5y = 300 and 3x + 7y = 285 represent the money collected from selling gift baskets in a school fundraising event (in dollars). If x represents the cost for each snack gift basket and y represents the cost for each chocolate gift basket, what is the cost for each chocolate gift basket?
The cost is $30
The name of the women from the cafeteria
Paqui
x/5 + 3(x - 1)/2 = 2(x - 3)
x = 75/33
(x + 3)^2 = 7
x = -3 + sqrt(7) and x = -3 - sqrt(7)
What is the solution for x + y = 2 and 2x + 2y = 4?
All real numbers
