If
x+y=-4
y-3x=16 or we cn write as
x+y=-4
-3x+y=16
i multiply the first equation by 3
3x+3y=-12
-3x+ y=16
4y=4
y=1
x+1=-4
x=-5
First of all youre not going to get a direct answer to all of these questions, youre going to have 3 finally equations(because thats the amount of variables you have).
Answer:
C= to find x, add the given angles
Step-by-step explanation:
First you distribute the six
-138>-36b+42
Then you subtract 42
-180>-36b
Next, you divide by -36 and since you are dividing by a negative, you turn the sign around
