Question

Please solve this problem and find the value of x​

Answer 1

Answer:

x = 5

Step-by-step explanation:

Since the base angles are congruent then the triangle is isosceles with the 2 legs being congruent, then

9x - 5 = 4x + 20 ( subtract 4x from both sides )

5x - 5 = 20 ( add 5 to both sides )

5x = 25 ( divide both sides by 5 )

x = 5

Answer 2

Answer:

Step-by-step explanation:

ok for this-

the equation is:

9x-5+4x+20

Step 1: Combine like terms

=9x+4x-5+20

Step 2: Add the numbers: -5 + 20 = 15

=9x+4x+15

=13x+15

Step 3: Divide 13x by 13 and 15

$= \frac{13x}{13} + \frac{15}{13}$

= 1.15 = x
