Mathematical Reasoning第 50 / 120 题
Solve the inequality: 2x − 3 < 7.
a.x < 2
b.x < 5
c.x > 5
d.x < 10
解析
Add 3 to both sides to get 2x < 10, then divide by 2 to get x < 5. When dividing an inequality by a positive number, the direction of the sign stays the same. The solution is all values less than 5.
