Answer:
x = 75
Step-by-step explanation:
Given information from the question:
x - 3y = 30
y = 15
We can substitute y = 15 into the equation to find x.
x - 3(15) = 30
x - 45 = 30
x - 45 + 45 = 30 + 45
x = 75
I'm pretty sure you can just use a Cartesian plane and since all of your points are (positive, positive) they'd all be in the First Quadrant (top right)
(n / 10) + 15
The quotient is the result of division between two numbers
Answer:
y= 6
Step-by-step explanation:
1. Rearrange the terms before the equal sign: 14+y=3y+2-> y+14=3y+2
2. Subtract 14 from both sides: y+14=3y+2-> y=3y-12
-14 -14
3. Subtract 3y from both sides: y=3y-12-> y-3y= -12
-3y -3y
4. Combine like terms: y-3y= -12-> -2y= -12
1-3 keep the y
5. Divide both sides by -2: -2y= -12-> y= 6
/2 /2
6. So, you're left with y= 6
-28x-11
Step-by-step explanation:
10x-38x=-28x
+36-47=-11
so the answer is -28x-11
