Answer:

8x -24 = 9y

Step-by-step explanation:

We assume your equation is ...

2/3x -2 = 3/4y

Fractions can be eliminated by multiplying the equation by the least common denominator of the fractions.

LCM(3, 4) = 12

Multiplying the equation by 12 gives you ...

12(2/3x -2) = 12(3/4y)

8x -24 = 9y

(7p^(2)+3p)-(5p^(2)+4)<br> solve for standard form and show how you got it

inna [77]

$\huge \boxed{\mathfrak{Question} \downarrow}$

$( 7 p ^ { 2 } + 3 p ) - ( 5 p ^ { 2 } + 4 )$ . Solve for standard form.

$\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}$

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

To find the opposite of 5p²+4, find the opposite of each term inside the bracket.

$7p^{2}+3p-5p^{2}-4$

Combine 7p² and -5p² to get 2p².

$\boxed{ \boxed{ \bf \: 2p^{2}+3p-4 }}$
