Question

Solve the equation 

5(- 3x - 2) - (x - 3) = -4(4x + 5) + 13​

Answer 1

Given the equation

5 (- 3 x - 2) - (x - 3) = - 4 (4 x + 5) + 13

Multiply factors.

-15 x - 10 - x + 3 = - 16 x - 20 + 13

Group like terms.

- 16 x - 7 = - 16 x - 7

Add 16x + 7 to both sides and write the equation as follows

0 = 0

The above statement is true for all values of x and therefore all real numbers are solutions to the given equation.

Answer 2

${\huge{\red{\mathfrak{answer}}}}$

y=-x-13

4x-3y=-17

----------------

Substitute for "y" and solve for "x":

4x - 3(-x-13) = -17

---

4x + 3x + 39 = -17

7x = -56

x = -8

------------------

Since y = -x-13, y = 8-13 = -5

---

Solution: (-8,-5)
