2(5-3v)+9v=28 step by step please

Irina-Kira [14]

First, distribute the 2 across the parenthesis.
10-3v+9v=28
Combine like terms on the left.
10+6v=28
Start to get the numbers on the right and the v alone on the left by moving the 10 to the right.
6v=28-10
6v=18
Divide to get the v alone.
v=3

Hope that helps.

Answer:

x ≥ -4

Step-by-step explanation:

-3x + 2 ≤ 14

Subtract 2 from each side

-3x+2-2 ≤ 14-2

-3x ≤ 12

Divide each side by -3 . Remember that dividing by a negative flips the inequality.

-3x/-3 ≥12/-3

x ≥ -4
