Answer:
x=-6 and y=-3
mrk me brainliest plz
Step-by-step explanation:
Step: Solve−3x+y=15 for y:
−3x+y=15
−3x+y+3x=15+3x (Add 3x to both sides)
y=3x+15
Substitute 3x+15 for y in−3x+7y=−3:
−3x+7y=−3
−3x+7(3x+15)=−3
18x+105=−3(Simplify both sides of the equation)
18x+105+−105=−3+−105 (Add -105 to both sides)
18x=−108 divide both side by 18
x=-6
<em><u>Answer:</u></em>
yellow line
<em><u>Explanation:</u></em>
<u>The flow of cars within a road can be represented by either of two ways:</u>
<u>1- single broken white line:</u>
This indicates that the flow of cars in both lanes is in the <em>same direction</em>
<u>2- single broken yellow line:</u>
This indicates that the flow of cars in both lanes is in <em>opposite directions</em>
This can be simply visualized using the attached image where the green arrows indicate the direction of the movement of cars.
Hope this helps :)
