Answer: 18:6
Step-by-step explanation:
A) 3x + 4 = 5x - 10. It's easy to identify the lines' equations by their y-intercept and slope.
I have no clue. What is it?
12+11x=17x11x+12=17x
(both sides of the equation)
11x+12−17x=17x−17x
(Subtract 17x from both sides)
−6x+12=0−6x+12−12=0−12
(Subtract 12 from both sides)
−6x=−12−6x−6=−12−6
(Divide both sides by -6)
x=2
