Pulling my hair, need help!
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
4x=8 and 5y=15
02.x+0.4y=1.7 and 8.3x-6.3y=-4.3
x=1.93 and y=1.31
