One solution. One. Ask me if you have any questions
We have to consider the Order of Operations
And Divide the question into different parts
So we first do the Exponent:
= 32
(3×32-26)=(96-26)=70
Solve the parts in parenthesis
(8-(4-9)=(8-(-5)=(8+5)=13 (minus and minus becomes addition)
Distribute 7
7(13)=91
Now put the equation and equate everything
(3×+13(-2))+7(8-(4-9)=70+91=161
Final Answer=161
