Answer:
3
Step-by-step explanation:
Simplifying
5x + -2 = 3x + 4
Reorder the terms:
-2 + 5x = 3x + 4
Reorder the terms:
-2 + 5x = 4 + 3x
Solving
-2 + 5x = 4 + 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
-2 + 5x + -3x = 4 + 3x + -3x
Combine like terms: 5x + -3x = 2x
-2 + 2x = 4 + 3x + -3x
Combine like terms: 3x + -3x = 0
-2 + 2x = 4 + 0
-2 + 2x = 4
Add '2' to each side of the equation.
-2 + 2 + 2x = 4 + 2
Combine like terms: -2 + 2 = 0
0 + 2x = 4 + 2
2x = 4 + 2
Combine like terms: 4 + 2 = 6
2x = 6
Divide each side by '2'.
x = 3
Simplifying
x = 3
Answer:
18

Answer:
12.60
Step-by-step explanation:
Start off by the total which is 18. To find the percentage off you will have to make the 30% into a decimal, so simply move it two spaces to the left. Now you have .30. Multiply the decimal, .30, and the full amount, 18. Your equation now should be (.30)*(18). Your answer will be 5.40. 5.40 is what is off of the shirt from the original price, so subtract 5.40 from 18. Your equation now is (18-5.40) which is 12.60.
