Answer:
x=5/2 + a/2, y= 5/2 - a/2
Step-by-step explanation:
We can solve this system using addition of the equations
x+y=5
<u>x-y=a</u>
2x =(5+a)
x=(5+a)/2= 5/2 +a/2
x=5/2 +a/2
x-y=a
y = x - a , x=5/2 + a/2
y= 5/2 + a/2-a
y= 5/2 - a/2

Answer:
g = -32
Step-by-step explanation:
3 = g/-4 - 5
Multiply both sides of the equation by -4
-12 = g + 20
Swap sides so that the variable terms are on the left hand side
g + 20 = -12
Subtract 20 from both sides
g = -12 - 20
Subtract 20 from -12 to get -32
g = -32
Answer:
Option B, 1/4 (x - 5) = 13
Step-by-step explanation:
