Answer:
x ≥ 3
Step-by-step explanation:
Sentence to Algebra:
Two times a number = 2x
Plus one = + 1
At least 7 = ≥ 7
Algebraic Equation: 2x + 1 ≥ 7
Solve for x:
2x + 1 ≥ 7 [tex]\longmapsto[/tex] Subtract 1 from both sides
2x + 1 - 1 ≥ 7 - 1
2x ≥ 6 [tex]\longmapsto[/tex] Divide both sides by 2
2x ÷ 2 ≥ 6 ÷ 2
x ≥ 3
