Hello
-4x + 11y = 15
x = 2y
Ok, we need to solve x = 2y for x
Lets start by substitute 2y for x in -4x + 11y = 15
-4x + 11y = 15
-4(2y) + 11y = 15
-8y + 11y = 15
3y = 15
Divide both sides by 3
3y/3 = 15/3
Y = 5
Again, substitute 5 for y in x= 2y
x = 2y
x = 2(5)
x = 10
Final answer : X = 10 and y = 5
Good luck!
The answer is 6 because 5 candies go's up by three so you would add 3 to 3 3+3
Answer:
C. 
Step-by-step explanation:
Replace x with a + 2 and simplify the expression.
Let x = a + 2
The measure of m<CBD is 63 degrees
<h3>Circle Geometry</h3>
According to line geometry, the sum of angles on a straight line is expressed as:
arcCD + m<CBF = 180
Given that
arcCD= 5x + 3 and;
m<CBF = 11x - 15
Substitute
5x + 3 + 11x - 15 = 180
16x - 12 = 180
16x = 192
x = 12
Determine the measure of m<CBD
m<CBD = arc CD = 5x + 3
m<CBD = 5(12) + 3
m<CBD = 63 degrees
Hence the measure of m<CBD is 63 degrees

X=5+y
Substitute the value of x in second equation
28x – 9y= -12
28 (5+y)-9y =-12
140 +28y -9y =-12
140 +19y= -12
19y = - 152
y= -8
Now let's find the value of x using y
x= 5+y
x= 5 + (-8)
= -3
So,
x= -3
y=-8
