X=4, y=28. 7x=2x+20, so subtract 2x from both sides and you’ll get 5x=20. Divide both sides by 5 and you’ll get x=4. Substitute this into the other equations and they will both equal 28.
The answer is 2x+6
Explanation: 2 times 3 is 6 and 2 times x is 2x
Answer:
Answer is D

Answer:
Step-by-step explanation:
The sum of a triangle's interior angles is 180
. From the figure, we can see that one of the angles is a right angle. The remaining two are x and y. By adding these together, we can equate their sum with 180.
x+y+90=180b
Using the equation found in part A and the given equation, we can form a system of equations.
