Answer:

x²y²+xy²+3+xy+2y²

Step-by-step explanation:

(2x²y²+x²y+xy²+3)-(x²y²+x²y²+x²y-xy-2y²)

1. remove the parentheses (when there’s - in front of an expression in parentheses change the sign of each term of the expression)

2x²y² + x²y + xy² + 3-x²y² - x²y² - x²y + xy - 2y²

2. eliminate the opposites

2x²y² + xy² + 3 -x²y² + xy +2y²

3. collect like terms

x²y² + xy² + 3 + xy + 2y²

What is 1/6x=4 in solving equations with rational coefficients

Debora [2.8K]

To solve an equation with a rational (fraction) coefficient you need to multiply both sides of the equation by the reciprocal (invert the fraction - flip it).

$\frac{1}{6}x =4$ The reciprocal of 1/6 is 6/1 or 6
$6( \frac{1}{6} x)= 6(4)$ The product of reciprocals equals 1
1x = 24
x = 24
