In the step after -6x+10=4x+20, he moved the terms incorrectly. you have to add 6x to both sides so it would be 10=4x+6x+20 which simplifies to 10=10x+20. subtract 20 from both sides to get -10=10x. divide both sides by 10. the answer is x=-1
-2 / 5y = 4
Multiply both sides by 5y:
-2/ 5y * 5y = 4 * 5y
refine: -2 = 20 y
Switch sides:
20 y = - 2
Divide both sides by 20
20 y / 20 = - 2 / 20
y = -1/10
hope this helps!
Point-slope form
y-y₀=m.(x-x₀)
P(3,5)
m=2
y-5=2(x-3)
The answer is 269. Hope this helped!! Could I possibly get brainliest!? :)
