For the systems of linear equations in questions the following questions:

Determine how many solutions exist

Use either elimination or substitution to find the solutions (if any)

4x = 8 and 5y = 15

0.2x + 0.4y = 1.7 and 8.3x - 6.3y = -4.3

x/3 - y/5 = 4 and 3x/4 + 2y/3 = 6

  • Algebra -

    4x=8 and 5y=15
    x=2 y=3
    02.x+0.4y=1.7 and 8.3x-6.3y=-4.3
    x=1.93 and y=1.31
