Answer:

I can help you because I am learning the same time. ok

Step-by-step explanation:

1 step (5x-2) = (8x-7)

expand (8x-7) = 8x-7 so 5x-2=8x-7

add 2 to both side 5x-2+2=8x-7+2

simplify 5x=8x-5

subtract 8x from both side 5x-8=8x-5-8

simplify -3x=5

divide both sides by -3

3x 3 =5x

simplify x=5 over 3

MrRa [10]

Answer:

6 $x^{5}$ + 5x² - 2x + 3

Step-by-step explanation:

Given

( $x^{5}$ + 2x² - 4) - (-5 $x^{5}$ - 3x² + 2x - 7)

Remove the parenthesis on the first factor and distribute the second by - 1

= $x^{5}$ + 2x² - 4 + 5 $x^{5}$ + 3x² - 2x + 7 ← collect like terms

= 6 $x^{5}$ + 5x² - 2x + 3 ← in standard form
