Replace the second equation y=3x+4 into the first one:
2(3x+4)+5x=30
Now solve for x:
6x+8+5x=30
11x=30-8
11x=22
x=22/11
x=2
Finally, replace x=2 into y=3x+4
y=3*2+4
y=6+4 = 10
So the anwer is x=2, y=10
Answer:
60°
Step-by-step explanation:
90°+30°=120°
180°_120°=60°
You would put in 12 for x since there are 12 months in a year. Then you would multiply 12 by 35, and add 70.
