x=5
Step-by-step explanation:
19x + -18 = 7x + 1 + 10x + -9
Reorder the terms:
-18 + 19x = 7x + 1 + 10x + -9
Reorder the terms:
-18 + 19x = 1 + -9 + 7x + 10x
Combine like terms: 1 + -9 = -8
-18 + 19x = -8 + 7x + 10x
Combine like terms: 7x + 10x = 17x
-18 + 19x = -8 + 17x
Solving
-18 + 19x = -8 + 17x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-17x' to each side of the equation.
-18 + 19x + -17x = -8 + 17x + -17x
Combine like terms: 19x + -17x = 2x
-18 + 2x = -8 + 17x + -17x
Combine like terms: 17x + -17x = 0
-18 + 2x = -8 + 0
-18 + 2x = -8
Add '18' to each side of the equation.
-18 + 18 + 2x = -8 + 18
Combine like terms: -18 + 18 = 0
0 + 2x = -8 + 18
2x = -8 + 18
Combine like terms: -8 + 18 = 10
2x = 10
Divide each side by '2'.
x = 5
Simplifying
x = 5
