Multiply 2x+3y=-1 by 5 and 3x-5y=10 by 3
3y*5=15y and -5y*3=-15y
Add -15y and 15y you have no y values left.
Your main focus is going to be on the y values. What can you multiply each y value by to get the same number so that when you add the positive and negative you get 0.
Answer:
8
Step-by-step explanation:
f(x)=2x^4-4x^3-11x^2+3x-6
f(-2)=2(-2)^4-4(-2)^3-11(-2)^2+3(-2)-6
f(-2)=2(16)-4(-8)-11(4)-6-6
f(-2)=32+32-44-12
f(-2)=64-44-12
f(-2)=20-12
f(-2)=8
Putting this in mathematical terms
(-5)x/2-5=-55
Multiplying throughout by ‘-1’
(5x)/2+5=55
5x/2=50
x=+20
Thus 20 is the required value of x.
