Simultaneous Equations: Quiz 4
Use the substitution method to find the values of x and y in all of the simultaneous equations below.
1) y = x2 + 2
y = 3x + 6
2) y = x2 – 4
y = -3x
3) y = x2 + 4x
y = 2x – 1
4) y = 2x2 + 2x + 10
y = x2 – 4x + 2
5) y = x2 + 2
y – x = 8
6) y – 5x – 1 = 0
y = 2x2 – 2
7) x + 7y = 14
y2 + x = 4
hint: Substitute in for y
8) x2 + y2 = 5
y = x + 3
9) y = x2 + 4x
y = 3x + 6
