Question

39+а×(42÷7)-(19+18)=26

Answer 1

39+а·(42:7)-(19+18)=26
39+а·6-37=26
6а=26-39+37
6а=24
а=24:6
а=4
39+4·(42:7)-(19+18)=39+4·6-37=39+24-37=26

Answer 2

Let's solve the expression step by step:

1. First, perform the operations inside the parentheses: 42 ÷ 7 = 6

2. Now, the expression becomes: 39 + а × 6 - (19 + 18) = 26

3. Next, simplify the addition and subtraction inside the parentheses: 19 + 18 = 37

4. The expression is now: 39 + а × 6 - 37 = 26

5. Now, move the constant term to the other side of the equation: 39 + а × 6 = 26 + 37 39 + а × 6 = 63

6. Subtract 39 from both sides to solve for "а": а × 6 = 63 - 39 а × 6 = 24

7. Finally, divide by 6 to find the value of "а": а = 24 ÷ 6 а = 4

So, the value of "а" that makes the equation true is 4.
