Answer:
The solution to the equation 7x [6+10(1+1)] = 4 x 5 is x = 10/91.
Explanation:
o solve the equation 7x [6+10(1+1)] = 4 x 5, we can use the order of operations, which tells us to first perform the operations inside the parentheses, then the multiplication and finally the multiplication by 7x.
So, we have:
7x [6+10(1+1)] = 4 x 5
7x [6+10(2)] = 20
7x [6+20] = 20
7x [26] = 20
182x = 20
To solve for x, we can divide both sides by 182:
182x/182 = 20/182
x = 20/182
Simplifying the fraction by dividing both the numerator and denominator by their greatest common factor, we get:
x = 10/91
Therefore, the solution to the equation 7x [6+10(1+1)] = 4 x 5 is x = 10/91.
