Answer:
x = -7/5 y = -6/5
Step-by-step explanation:
System:
y = -2x-4
AND
y= 3x+3
therefore -2x-4 = 3x+3
-2x-3x = 3 + 4
-5x = 7
x = -7/5
y = 3(-7/5) + 3 = -21/5 + 3 = -6/5

Answer:
= z/12 - 1/3
Step-by-step explanation:
z-4/(4+8)
= z-4/12
= z/12 - 4/12
= z/12 - 1/3
The little square means a right angle which is equal to 90 degrees.
X + 30 = 90
