Need to see the number line to help you
You would subtract 7 from 16 which would equal 9 so x=9
Answer: x=36
Simplifying
6x + 27 = 7x + -9
Reorder the terms:
27 + 6x = 7x + -9
Reorder the terms:
27 + 6x = -9 + 7x
Solving
27 + 6x = -9 + 7x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-7x' to each side of the equation.
27 + 6x + -7x = -9 + 7x + -7x
Combine like terms: 6x + -7x = -1x
27 + -1x = -9 + 7x + -7x
Combine like terms: 7x + -7x = 0
27 + -1x = -9 + 0
27 + -1x = -9
Add '-27' to each side of the equation.
27 + -27 + -1x = -9 + -27
Combine like terms: 27 + -27 = 0
0 + -1x = -9 + -27
-1x = -9 + -27
Combine like terms: -9 + -27 = -36
-1x = -36
Divide each side by '-1'.
x = 36
Simplifying
x = 36
