Answer: (-8, - 80)
Step-by-step explanation:
y = 10x
y = - 3x - 104
Substitute "y" with "10x" into the second equation, then solve for x:
10x = - 3x - 104
13x = - 104 added 3x to both sides
x = - 8 divided both sides by 13
Next, substitute - 8 for x into the first equation to solve for y:
y = 10 (-8)
= - 80
