Answer:
10.5
Step-by-step explanation:
[tex]2(x + 4) = 50 [/tex]
[tex]4x + 8 = 50 [/tex]
[tex]4x = 50 - 8[/tex]
[tex]4x = 42[/tex]
[tex]x = 42 \div 4[/tex]
[tex]x = 10.5[/tex]
Answer:
Simplifying
2(x + 4) = 50
Reorder the terms:
2(4 + x) = 50
(4 * 2 + x * 2) = 50
(8 + 2x) = 50
Solving
8 + 2x = 50
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-8' to each side of the equation.
8 + -8 + 2x = 50 + -8
Combine like terms: 8 + -8 = 0
0 + 2x = 50 + -8
2x = 50 + -8
Combine like terms: 50 + -8 = 42
2x = 42
Divide each side by '2'.
x = 21
Simplifying
x = 21
This took a long time to type and i think it is wrong but hope this helps. hint, hint.
