Question

If 5r + 4 = -4 – (6r – 8), then –4r = ? a)12 b) -2 c)-8 d) 0

Answer 1

Answer:

$-4r = 0$

Step-by-step explanation:

Given

$5r + 4 = -4 - (6r - 8)$

Required

Find - 4r

$5r + 4 = -4 - (6r - 8)$

Open bracket

$5r + 4 = -4 - 6r + 8$

Collect Like Terms

$6r+5r =- 4 -4 + 8$

$11r =0$

Solve for r

$r = \frac{0}{11}$

$r = 0$

Multiply both sides by -4

$-4r = 0*-4$

$-4r = 0$
