Question

Which number make this number sentence true (4+5)+3=(2+3)+​
please help

Answer 1

7

Explanation:

Let x stand for the unknown number

(4+5)+3=(2+3)+​x

First, solve the numbers in paratheses,

(4+5)+3=(2+3)+

9+3=5+x

Then combine like terms

12=5+x

Finally, subtract 5 from both sides

12-5=5-5+x

7=x, therefore 7 makes the statement true.
