Question

Given the figure below, find the values of x and z.

(6x + 23) ⁰
(9x + 37) ⁰
z ⁰
X =
Z=

Answer 1

So, x = -11/3 and z = 1.

Explanation:

⁰ (zero exponent), which means the values inside the parentheses should be equal to 1.

Therefore:

6x + 23 = 1

9x + 37 = 1

z = 1

Solving for x in the first equation:

6x + 23 = 1

6x = 1 - 23

6x = -22

x = -22/6

x = -11/3

Solving for x in the second equation:

9x + 37 = 1

9x = 1 - 37

9x = -36

x = -36/9

x = -4

So, x = -11/3 and z = 1.
