Answer:

y = 15

Step-by-step explanation:

x + y + z = 45 → (1)

Given

y = \frac{1}{2}(x + z)

Multiply both sides by 2 to clear the fraction

2y = x + z ← substitute into (1)

2y + y = 45

3y = 45 ( divide both sides by 3 )

y = 15

What is the slope of the line whose equation is 12 equals 4x - 3 y?
lisov135 [29]
12=4x-3y Begin by moving the 4x away from the y. -3y=-4x+12. To get y by itself, divide both sides by -3. y= 4/3x -4. Therefore the slope is 4/3.
