Answer: x=-2 y=2
Step-by-step explanation:
I decided that isolating the y value of the second equation is the best way to start solving.
I divide 3 from both sides to get y= (4-x)/3. With this, I can substitute into the first equation. 4x+3(4-x)/3)=-2.
The multiplying the 3 by the denominator three cancels each other out to make:
4x+4-x=-2.
We subtract 4 on both sides and then subtract x from 4x.
We end up with 3x=-6. Then, we divide both sides by 3.
x=-2.
Now we substitute this into the second equation to solve.
3y=4-(-2)
This becomes 3y=4+2 which is 3y=6
We divide both sides by 3 to get y=2
We end up with x=-2 and y=2.
I hope you learned something :)
Answer:
<em>m∠1 = 90°</em>
<em>m∠2 = 35°</em>
<em>m∠3 = 55°</em>
Step-by-step explanation:
Find the diagram attached
From the diagram:
Given that <4 = 35°
The sum of the angle on a straight line at point A is 180°. Hence:
The sum of angle in the triangle ABC is 180°, hence;
