Answer:
Replace one equation with the sum/difference of both equations and Yes
Step-by-step explanation:
In Khan Academy
Basically to solve this, you set both equations equal to each other and solve because the angles are the same.
5x+7=8x-71
isolate x by adding 71 to both sides and subtracting 5x from both sides
3x= 78
divide 78 by 3
x=26
STEP BY STEP:
13x - 8 + 7x – 2 = 11+ 6x -- 14x – 5
Combine like terms
20x-8-2 = 20x+11-5
20x-10 = 20x+6
Subtract with -20x on both sides and the result is:

The answer is NO SOLUTION
The equation to find the right triangle is a^2+b^2=c^2 or the Pythagorean Theorem.
a^2+b^2=c^2 Substitute the values
18^2+26^2=c^2 Solve the powers
324+676=c^2 Simplify
1000=c^2 Solve the the square
31.6=c
