Find the point of intersection of the two lines.
-4x + 4 = 4y
y = 2x
Use the elimination method to solve the system of equations.
x + y = 7
2x + y = 11
How do you solve this system of non-linear equations?
x² + y² = 25
2x + 4y = -10
A fashion designer makes and sells hats. The material for each hat costs $5.50. The hats sell for $12.50 each. The designer spends $1400 on advertising. How many hats must the designer sell to break even?
How do you solve the system of equations:
y = 2x - 4
y = 4x - 10
Find the solution to the system by the substitution method.
3x – 5y = 7
x – 4y = -7
How do you solve the system with the substitution method?
x - y = 10
-x - y = 20
Solve the system of equations for x and y:
y = 3x
2x - 3y = 14
How do you solve this system of equations using the substitution method?
3x - 4y = 10
y = x - 3
How do you solve these with the substitution method?
4x - y = -14
y = 8x + 7
