Answer:
x = 24
Step-by-step explanation:
In a radical equation it is critical to start by isolating the root that contains the unknown on one side of the equal sign, so we do such by adding 3 to both sides:

Next we square both sides of the equation to free the unlnown from the square root:

We found x by adding 8 on both sides. Therefore x=24.
One can check the answer by replacing x by 24 in the original equation.
Answer:
Step-by-step explanation:
4y - 2(5 - y + 4) = 4y - 2(9 - y)
= 4y + 9*(-2) - y *(-2)
= 4y - 18 + 2y {Combine like terms 4y and 2y}
= 6y - 18
6y - 18 = 6*y - 6*3
= 6(y - 3)
6y- 18 = 2 *3y - 2*9
= 2(3y -9)
2(3y - 9) and 6(y- 3 ) are equivalent to 4y - 2(5- y +4)
Others are not equivalent
Answer:
4(6q-19u-13b+17i)
Step-by-step explanation:
each of the variables is divisble by 4, thus allowing you to factor out 4.
