Given:
4.5(4−)+36=202−2.5(3+28)
Solution:
In order to solve the given numerical equation, we apply the rules of PEMDAS, which stands for parenthesis, exponent, multiplication, division, addition, and subtraction.
4.5(4−)+36=202−2.5(3+28)
-18 + 36 =202 -2.5(31)
18 = 202 - 77.5
18 = 124.5
Transpose 18 on the other side of the equation, note that when transposing a number, the sign changes.
= 124.5 - 18
=106.5
Final answer:
=106.5
