Answer:

-3(x+2)-7 = 5x + 7

-3x - 6 - 7 = 5x + 7

-3x - 13 = 5x + 7

-20 = 8x

x = -2.5

Answer:

Exact form = x=-5/2

Decimal form = x=-2.5

Mixed number form = x=-2 1/2

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

-3(x+2)-7 = 5x + 7

-3x - 6 - 7 = 5x + 7

-3x - 13 = 5x + 7

-20 = 8x

  Divide both sides by 8 to get x by itself

The equation |ax + b| = c must have ?
ArbitrLikvidat [17]

Answer:

0, 1, or 2 solutions

Step-by-step explanation:

The equation |ax + b| = c

The equation have absolute value symbol

Absolute value always gives us the positive number.

For absolute value function , we need to consider two cases

positive and negative.

|x|=x  for positive ,  and |-x|=x for negative case

For negative case we include negative sign

So  |ax + b| = c can be written as 2 equations

(ax+b)=c                                  (ax+b)=-c

So we will get maximum of 2 solutions

The equation |ax + b| = c must have 0, 1, or 2 solutions
