Answer 1

Step-by-step explanation:

6x-2x-6x-12+15x-30=0

13x=18

x=18/13

Answer 2

Given question-:

2(x3-x)-3(x2+4)+5(x3-6)

we have to evaluate the above equation

so let's try to solve the question

$2( {x}^{3} - x) - 3( {x}^{2} + 4) + 5 ({x}^{3} - 6)$

$2 {x}^{3} - 2x - 3 {x}^{2} - 12 + 5 {x}^{3} - 30$

$2 {x}^{3} + 5 {x}^{3} - 3{x}^{2} - 2x - 12 - 30$

$7 {x}^{3} - 3 {x}^{2} - 2x - 42$

Hope this will help you
