Answer:
)
Step-by-step explanation:
This system we can solve by substitution method :
y=13x-1
y=9x+4
_______
y=13x-1
13x-1=9x+4 (instead y in second equation we use 13x-1 and first rewrite)
_______
y=13x-1
13x-9x=4+1 (subtract 9x and add 1 for each side)
______
y=13x-1
4x=5 (divide by 4)
_____
y=13x-1
(instead x in first eq we write 5/4)
______
