Answers
Step-by-step explanation:
Simplifying
9x + -13 = 11x + 27
Reorder the terms:
-13 + 9x = 11x + 27
Reorder the terms:
-13 + 9x = 27 + 11x
Solving
-13 + 9x = 27 + 11x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-11x' to each side of the equation.
-13 + 9x + -11x = 27 + 11x + -11x
Combine like terms: 9x + -11x = -2x
-13 + -2x = 27 + 11x + -11x
Combine like terms: 11x + -11x = 0
-13 + -2x = 27 + 0
-13 + -2x = 27
Add '13' to each side of the equation.
-13 + 13 + -2x = 27 + 13
Combine like terms: -13 + 13 = 0
0 + -2x = 27 + 13
-2x = 27 + 13
Combine like terms: 27 + 13 = 40
-2x = 40
Divide each side by '-2'.
x = -20
Simplifying
x = -20
Answer:
9x-13=11x+27
9x-11x= 27+13
-2x= 40
x= -20
check
LHS = 9(-20)-13
= -180-13
= -193
RHS= 11(-20)+27
= -220+27
= -193
this is the correct answer
