How do you solve this equation ?
nata0808 [166]
The first step to solving this is to solve the equation for x
x = - 21/5 - y
4x + 4y = -14
now,, substitute the given value of x into the equation "4x + 4y = -14"
4( - 21/5 - y) + 4y = -14
next,, solve the equation for y
y∈∅
since this system has no solution for y, your answer is (x,y)∈∅
let me know if you have any further questions

Do you think that subliminal messages should be banned from advertising?Why or why not? Will mark the brainliest!!!
Murrr4er [49]

Answer:

yes

Step-by-step explanation:

I believe consumers and targets of these ad campaigns should know EXACTLY what they are buying. They need to be intrigued by the ad without the use of Subliminal Messages because with these tricks, big companies can trick and manipulate people and consumers into buying many things. For example they can buy fast food, sweets, and perhaps medicines that don't even work.
