Solve the system of linear equations by substitution. x=16−4y 3x+4y=8

Solution: (-4,5)

Step-by-step explanation:

x=16-4y

3x+4y=8

The 1st equation tells you x = 16-4y

---

Substitute that into the 2nd equation

and solve for "y":

3(16-4y)+4y = 8

48 - 12y + 4y = 8

-8y = -40

---

y = 5

---

Solve for "x"

x = 16-4y

x = 16-4*5

x = 16-20

x = -4

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680
