how to solve this equation by inserting the brackets to make it a true statement
-20+4x2+7-35 = -19
-20+(4x(2+7))-35 = -19
-20+36-35 = -19
3×4-1+2=11
To solve the equation by inserting brackets to make it a true statement, you need to follow the order of operations (PEMDAS/BODMAS).
Step 1: Start with the given equation:
-20 + 4 * 2 + 7 - 35 = -19
Step 2: Identify the multiplication operation first. We have 4 * 2, which equals 8. Insert brackets around this operation to isolate it:
-20 + (4 * 2) + 7 - 35 = -19
Step 3: Evaluate the operation inside the brackets:
-20 + 8 + 7 - 35 = -19
Step 4: Continue solving the equation using addition and subtraction:
-20 + 8 + 7 - 35 = -19
-12 + 7 - 35 = -19
-5 - 35 = -19
-40 = -19
Step 5: Since we have reached an incorrect statement (-40 ≠ -19), we need to reassess our bracket placement.
In this case, it is not possible to rearrange the brackets to make the equation a true statement. It indicates that the original given equation does not have a solution.
