Question

Solve
3(2x - 5) = 9(10 - x)

Answer 1

Answer:

x=7

Step-by-step explanation:

3(2x - 5) = 9(10 - x)

6x-15=90-9x

6x+9x=90+15

15x=105

x=7

Answer 2

Answer:

$x = 7$

Step-by-step explanation:

First, we need to expand the brackets:

$3(2x-5)=9(10-x)$ (equation given)

$6x-15=90-9x$

$15x -15 = 90$ (add $9x$ on both sides)

$15x = 105$ (add $15$ on both sides)

$x = 7$ (divide by $15$ on both sides)

Hope this helps :)
