Question 580514
Solve this equation using the elimination method
y = 6x + 63
17x = -308 + 9y
You substitute (6x+63) for y, you no longer have y in the equation
17s = -308 + 9(6x+63)
17x = -308 + 54x + 567
17x - 54x = -308 + 567
-37x = 259
x = {{{259/(-37)}}}
x = -7
:
Find y
y = 6(-7) + 63
y = -42 + 63
y = 21
