Find the value of x 3x+20+4x-36
Answers
Answer:
Step-by-step explanation: solution for (3x+20)+(4x-36)=180 equation:
Simplifying
(3x + 20) + (4x + -36) = 180
Reorder the terms:
(20 + 3x) + (4x + -36) = 180
Remove parenthesis around (20 + 3x)
20 + 3x + (4x + -36) = 180
Reorder the terms:
20 + 3x + (-36 + 4x) = 180
Remove parenthesis around (-36 + 4x)
20 + 3x + -36 + 4x = 180
Reorder the terms:
20 + -36 + 3x + 4x = 180
Combine like terms: 20 + -36 = -16
-16 + 3x + 4x = 180
Combine like terms: 3x + 4x = 7x
-16 + 7x = 180
Solving
-16 + 7x = 180
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '16' to each side of the equation.
-16 + 16 + 7x = 180 + 16
Combine like terms: -16 + 16 = 0
0 + 7x = 180 + 16
7x = 180 + 16
Combine like terms: 180 + 16 = 196
7x = 196
Divide each side by '7'.
x = 28
Simplifying
x = 28olution for (3x+20)+(4x-36)=180 equation:
