Ierofanga [76]

Answer:

$x=-\dfrac{41}{14}$

Step-by-step explanation:

$7(2x+6)=1$

Expand parentheses:

$14x+42=1$

Subtract 42 from both sides:

$14x=-41$

Divide both sides by 14:

$x=-\dfrac{41}{14}$

Hope this helps!

-9/4 v + 4/5 = 7/8 v=? step by step need help asap please

Vesna [10]

-9/4v + 4/5 = 7/8; First, you subtract 4/5 from each side to have variable v on a side and numbers on the other: -9/4v = 7/8 - 4/5; -9/4v = 35/40 - 32/40; -9/4v = 3/40; Then you divide each side to get the variable v alone on a side, and one number on the other: V= (3/40) / (-9/4); Dividing to fractions is equal to multiplying the first one by the inverse of the second: V= (3/40) * (-4/9); V= -12/360; V= -1/30; You can re-check your answer (very important): (-9/4)*(-1/30)+4/5=7/8; The answer has been approved. Hope this helps! :)
