= 2x - 7 > 21
= 2x > 21 +7
= 2x > 28
= x > 28/2
= x > 14
Answer:
Simplifying
2x + 7 = 21
Reorder the terms:
7 + 2x = 21
Solving
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-7' to each side of the equation.
7 + -7 + 2x = 21 + -7
Combine like terms: 7 + -7 = 0
0 + 2x = 21 + -7
2x = 21 + -7
Combine like terms: 21 + -7 = 14
2x = 14
ANSWER= 14
