Answer:
The three methods most commonly used to solve systems of equation are substitution, elimination and augmented matrices. Substitution and elimination are simple methods that can effectively solve most systems of two equations in a few straightforward steps.

This is your generic run-of-the-mill sinusoidal function:
f(x) = sin(x)
This is the same sine function but with a phase shift of 3 units to the right:
f(x) = sin(x-3)
This is the sine function but with an amplitude of 4 units:
f(x) = 4sin(x)
This is the sine function but flipped across the x-axis:
f(x) = -sin(x)
Combine all these transformations to get:
f(x) = -4sin(x-3)
Answer:
x = 96
Step-by-step explanation:
Since GI is a midsegment then it is one half the measure of JK, that is
JK = 2GI, that is
x - 42 = 2(x - 69) ← distribute
x - 42 = 2x - 138 ( subtract x from both sides )
- 42 = x - 138 ( add 138 to both sides )
96 = x
