What is the answer to 2x+4y=16:4y=12
allsm [11]

Answer:

Here,

2x + 4y = 16....eqn \: i \\ 4y = 12....eqn \: ii

substituting the value of 4y in eqn i fron eqn ii

so eqn i becomes

2x + 12 = 16 \\ 2x = 4 \\ x = 2

So

y = 12 \div 4 = 3

Thus,

x = 2 \: and \: y = 3

...hope this helps:)

Please help! Please explain how to do this, I am so lost.
alexdok [17]
Ok, so we know that RST is equal to 6x+12
And RST is also equal to 78 + 3x-12
so we set them equal to each other

6x + 12 = 3x - 12 + 78
And simplify
3x = 54
x = 18

Finally, we solve for the angle with 18 for x

6(18) + 12
108 + 12
120

Hope this helps
