Hello!
The problem is asking that we add the following two expressions:
(4.6x – 3) + (-5.3x + 9)
When adding or subtracting binomials, you need only to add or subtract similar terms. In this case, you will add the two coefficients of X (4.6 and -5.3) and the two constants (-3 and 9). Let’s try this first step now:
4.6x + (-5.3)x = (-0.7)x
Now we’ll add the two constants:
(-3) + 9 = 6
Now combine the two sums to create a single binomial expression:
-0.7x + 6
This is the sum of the two given binomial expressions.
I hope this helps!
