Answer:
3x+19
Step-by-step explanation:
2x are like terms and 4 and 15 are like terms so you add them together
Answer: x = 11
Step-by-step explanation:
1) Reorder the terms:
4 + 2x = 15 + x
2) Solving
4 + 2x = 15 + x
3) Solving for variable 'x'.
4) Move all terms containing x to the left, all other terms to the right.
5) Add '-1x' to each side of the equation.
4 + 2x + -1x = 15 + x + -1x
6) Combine like terms: 2x + -1x = 1x
4 + 1x = 15 + x + -1x
7) Combine like terms: x + -1x = 0
4 + 1x = 15 + 0
4 + 1x = 15
8) Add '-4' to each side of the equation.
4 + -4 + 1x = 15 + -4
9) Combine like terms: 4 + -4 = 0
0 + 1x = 15 + -4
1x = 15 + -4
10) Combine like terms: 15 + -4 = 11
1x = 11
11) Divide each side by '1'.
x = 11
12) Simplifying
x = 11
