Answer: 6x² + 5x + 3 • 2x² + 7x = 12x² + 12x
Explanation:
6x² + 5x + 3 • 2x² + 7x
Multiply 3 by 2 to get 6. (6x² + 5x + 6x² + 7x)
Add 6x² and 6x² to get 12x². (12x² + 5x + 7x)
Add 5x and 7x to get 12x. (12x² + 12x)
(x+5)/4=1/2
first get rid of the fraction
multiply both sides by 4
x+5=2
subtract 5
x=-3
(2x+1)/(4x-1)=2/3
get rid of the fractions,
multiply both sdies by (4x-1)(3)
(2x+1)(3)=(2)(4x-1)
distribute
6x+3=8x-2
subtract 6x form both sdies
3=2x-2
add 2
5=2x
divide by 2
5/2=x
