Answer:
x=14/3
Step-by-step explanation:
5x-y=6
+ -2x+y=8
----------------
5x+(-2x)-y+y=6+8
5x-2x-y+y=6+8
3x=14
x=14/3

Answer:
29
Step-by-step explanation:
Total marble = 36
Let red marbles be X
Then green marble is 4X + 1
And 4X + 1 + X = 36
5X = 36 - 1
5X = 35
X = 35/5 = 7
So, green marbles = 4X + 1
= 4(7) + 1
= 29

Answer:
Solution given:
the angles 2xº and 4yºare complementary
so
2x+4y=90°
dividing both side by 2we get
x+2y=45°
<u>the value of x + 2y</u><u> </u><u>i</u><u>s</u><u> </u><u>4</u><u>5</u><u>°</u><u>.</u>
