first, distribute -6 to (2b + 1), giving you -12b - 6, and then on the another side of the equation, distribute -2 to (5 + 4b) giving you, -10 - 8b. now we need to put our coefficients on one side so we will add 8b to each side of the equation, giving us -6 = -10 - 8b + 12b, then we will add 10 to both sides of the equation giving us, 10 -6 = -8b +12b, this gives u 4 = 4b. then, you would solve for b, which equals 1.
Answer:
The fourth option, 5x + 11y
Given:
(7x + 8y) - (2x - 3y)
Distribute the negative:
7x + 8y - 2x + 3y
Reorder terms (please note you cannot always do this, but we can here):
7x - 2x + 8y + 3y
Combine like terms:
5x + 11y
Answer:
5x + 11y
let's firstly conver the mixed fractions to improper fractions and then get their product.
hmmm I take it that one can write that mixed as .
is valid, not that it makes any sense.
Answer:
2/3 + ( -2 1/3) = -1 2/3
