The LCM for 8, 15, and 10 is 120.
Answer:
y=2
Step-by-step explanation:
if x=6 then 12-3y = 6 meaning y=2 because 12-6=6
Answer:
Y = 6 and x=6 are perpendicular because they both measure at a 90 degree angle
Answer:
a=-30
Step-by-step explanation:
So with this, I will be using the substitution method. With the first equation, substitute (y+3) into the x variable and solve for y:

Next, now that we have the value of y, substitute it into either equation to solve for x:

<u>And this is how you get your final answer (5,2).</u>
