Solve 4(2x - 1) - 3 = 9(x - 4). (1 point)

Mathematics
1 answer:
DiKsa [7]3 years ago
4 0

Answer:

x = 29

Step-by-step explanation:

First we will expand the equation using the rule

x(y - z) = xy - xz

Thus,

4(2x - 1) - 3 = 9(x - 4)

is equal to

8x - 4 - 3 = 9x - 36

Simplify:

8x - 7 = 9x - 36

Add 36 to both sides:

8x + 29 = 9x

Therefore,

x = 29

To find:

The money saved by Katherine.

2<br> — x = 6<br> 3<br><br> Any help? Please?
Mama L [17]
X = 9
you multiply both sides by 3 because you have to get rid of it and what you do to one side you do to the other then you divide both sides by 2 to isolate the variable. i hope that makes sense.
