Solve for r -10-5r+7r=10-8(-4r-5)

solve for

r, - 10 - 5 r + 7 r = 10 - 8 (- 4 r - 5)

r = - 2

Solution steps

- 10 - 5 r + 7 r = 10 - 8 (- 4 r - 5)

Add similar elements:

- 5 r + 7 r = 2 r

- 10 + 2 r = 10 - 8 (- 4 r - 5)

Expand

10 - 8 (- 4 r - 5) : 32 r + 50

- 10 + 2 r = 32 r + 50

Move

10

to the right side

2 r = 32 r + 60

Move

32 r

to the left side

- 30 r = 60

Divide both sides by

- 30

r = - 2

(\frac{- 14}{36}) (\frac{- ( 6 s )}{112})

\frac{700}{9}

5 x^{2} + 9 x = - 4

x, ∣ 2 x - 5 ∣ = 8

x, 0.5 + x = 1.5 - x
