Step 1
The given 3x1+27(7x2)=117.
The given phrase is an equation because it has an equal sign.
3x1+27(7x2)=117
7(3x1)+2(7x2)7=117
7(3x−1)+2(7x−2)=−11
21x−7+14x−4=−11
Step 2
Now, separate the variables on left side and constant of right side
21x+14x=−11+7+4
35x=−11+11
35x=0
x=0
Therefore, the value of x=0.
