Let Home runs = X
Triples would be X-3 ( 3 less triples than home runs)
Doubles would be 3x ( 3 times as many doubles as home runs)
Singles would be 45(x-3) ( 45 times as many singles as triples)
Simplify the equation for singles to be 45x-153
Now you have X + x-3 + 3x + 4x-135 = 262
Simplify:
50x - 138 = 262
Add 138 to both sides:
50x = 400
Divide both sides by 50:
x = 400/50
x = 8
Home runs = x = 8
Triples = x-3 = 8-3 = 5
Doubles = 3x = 3(8) = 24
Singles = 45(x-3) = 45(8-3) = 45(5) = 225

Answer:
49.0809
Step-by-step explanation:
Round it up to 49.10
Answer:
(-15, 13)
Step-by-step explanation:
-3(8x + 9y = -3)
4( 6x + 7y = 1)
-24x - 27y = 9
24x + 28y = 4 (add both equations)
y = 13
6x + 7*13= 1
6x + 91= 1
6x = 1 -91
x = -91/6
x = -15
