Question

simplify: 5(x-4)-3(x-4)+7(x-4)​

Answer 1

Answer:

5x-20-3x+12+7x-28

Step-by-step explanation:

=9x-36

Answer 2

$\longrightarrow \: simplify$

$5(x - 4) - 3(x - 4) + 7(x - 4)$

$= 5x - 20 - 3x + 12 + 7x - 28$

$= 9x - 36$

We can divide by 9 throughout , so that its easy for calculation

$= x - 4$

If we equate this by 0 { If its given in question}

$x - 4 = 0$

$therefore \: x = 4$
