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

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

you,
