Question

9•(a-5)+7•6=93+54÷9×8

Answer 1

9*(a-5)+7*6=93+54:9*8

9a-45+42=93+48

9a=93+48+45-42

 

 9a=144

 

 a=144:9

a=16

Answer 2

Answer 3

Let's solve the equation step by step:

9 • (a - 5) + 7 • 6 = 93 + 54 ÷ 9 × 8

First, let's simplify the right side of the equation:

93 + 54 ÷ 9 × 8 = 93 + 6 × 8 = 93 + 48 = 141

Now, let's simplify the left side of the equation:

9 • (a - 5) + 7 • 6

We'll simplify each multiplication and subtraction step by step:

9 • (a - 5) = 9a - 45

7 • 6 = 42

Now we can rewrite the equation:

9a - 45 + 42 = 141

Combine like terms:

9a - 3 = 141

Next, let's isolate the variable "a" by moving the constant term to the other side of the equation:

9a = 141 + 3 9a = 144

Finally, solve for "a" by dividing both sides of the equation by 9:

a = 144 ÷ 9 a = 16

Therefore, the value of "a" that satisfies the equation is a = 16.
