Solve: - 12 = -12(x + 2)
Fofino [41]

Answer:

x=-1

Step-by-step explanation:

-12=-12(x+12)

multiply -12 and x which equals -12x

Hitman42 [59]

Answer:

b=5

Step-by-step explanation:

  • We are going to use the basics of algebra to solve this

We need to isolate b by itself to find the value of b.

8b + 12 = 52

Subtract 12 from both sides

8b = 40

b = 5

Write 2 equivqlent fractions for 4/5
MaRussiya [10]
You can multiply the fraction by any number you want so the new fraction gonna be equivalent to your fraction like : (4 × 2)/(5 × 2) = 8/10 or  (4 × 3) / ( 5×3) = 12/15 so 4/5 = 8/10 = 12/15 :))
