y=2.8
x=5.7.....................................
Answer:
Yes both triangles are congruent thanks to SAS
we know XL and BC are congruent and AB and QX are congruent and the degrees are also congruent, since the angle is between the sides it's Side-Angle-Side(SAS)
Define x:
Let the sum be x
Construct the equation:
<span>The sum of 3 times a number and 5 is 2 times the number plus 15.
</span>→ 3x + 5 = 2x + 15
Solve x:
3x + 5 = 2x + 15 | Equation
x + 5 = 15 | Take away 2x from both sides
x = 10 | Take away 5 from both sides
Answer: The number is 10.
