考察能力
分步解法
- 1) Read the three equations and spot that the second one has a wrong operator.
- 2) Find the equals sign sitting in the third equation.
- 3) Drag that equals sign onto the plus sign in the second equation.
- 4) Confirm the second equation now balances correctly.
提示
查看提示
Check the operator in the second equation and where a spare equals sign can come from.
为什么有效
The second equation reads incorrectly because the plus sign should be an equals sign to make its numbers balance. The third equation happens to have the equals sign you need, so you move it over. Replacing the operator turns the faulty equation into a true statement.
