Question

8x - 1
4x + 5
2x + 11
. What is the value of x?

Answer 1

x = 3/2

Explanation:

Since this is an isosceles triangle, the length of two sides would be congruent.

Those two sides are represented with 8x - 1 and 4x + 5 respectively.

We can write the following equation based on the above mentioned information:

8x - 1 = 4x + 5

• Transfer like terms to the same side of the equation.

8x - 4x = 5 + 1

• Add/subtract expressions.

4x = 6

• Divide both sides by 4.

x = 6/4 this can be simplified to 3/2
