Answer:
x = 0
Step-by-step explanation:
Perform the indicated multiplication. We get:
20 - x = 5 + 15 + 21x
Combining like terms, we get:
0 = 21x, and so x must be 0.
x = 0
Answer:
x = 0
Step-by-step explanation:
20 - x = 5 + 3( 5 + 7x )
To solve the above equation, we will have to follow the step below.
First, we need to open the bracket
20 - x = 5 + 15 + 21x
Then we need to collect like terms, collecting like terms implies that we will move the values with x variables to the right side and we will move all the constant to the left-side.
20 - 5 - 15 = 21 x + x
0 = 22x
Divide both-side of the equation by 22 to get the bvalue of x
0/22 = 22x/22
0 = x
Therefore x = 0
