Examine the following systems of equations: Which three systems do you think would be the easiest
to solve? Why?
y = 4
A
E
Sy=-3x - 5
y = 4x + 30
3x + 4y = 10
x = 2y
F{ y = 3x - 2
x = 3y - 4
y = -2x +8
2x + y = 47
w
Which three systems do you think would be the most
difficult to solve? Why?
y = -2x + 5
{= 3x +7
K
x = -2y + 56
2x + 3y = 31
by = -3x + 10
y = -2x + 6
H
{ x = 2y - 15'(x+y = 10
