Use substitution to solve the system of equations.
3x+4y=-3
x+2y=-1

x = -1

y = 0

Step-by-step explanation:

x = -1 - 2y

3(-1 - 2y) + 4y = -3

-3 - 6y + 4y = -3

-3 - 2y = -3

- 2y = 0

y = 0

x + 2(0) = -1

x + 0 = -1

x = -1

(-1,0)

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
