-3x+y=10 is the answer. If you plug the coordinates in to the respective spots (-2 for x and 4 for y), you will get an equal true statement.
Answer:
x=7
Step-by-step explanation:
I believe we are solving for x. In that case, let us start by moving 1 to the other side.
Now, we want to get rid of that denominator of 5. Let us multiply both sides by 5:
Now, we may divide both sides by 4 to get rid of the coefficiant:
When we subtract both sides by 3, we get
x=7

The question is incomplete:
Before leaving to visit Mexico, Levant traded 270 American dollars and received 3,000 Mexican pesos. When he returned from Mexico, he had 100 pesos left.
How much will he receive when he exchanges these pesos for dollars?
Answer:
9 dollars
Step-by-step explanation:
To find the amount that Levant will receive when he exchanges these pesos for dollars, you can use a rule of three using the information provided:
270 dollars → 3,000 Mexican pesos
x ← 100 Mexican pesos
x=(270*100)/3,000=9 dollars
According to this, the answer is that he will receive 9 dollars.
