Answer:

b = −0.5

Step-by-step explanation:

Let's solve your equation step-by-step.

−3b+2.5=4

Step 1: Subtract 2.5 from both sides.

−3b+2.5−2.5=4−2.5

−3b=1.5

Step 2: Divide both sides by -3.

-3b/-3 = 1.5/-3

Well b would be -0.5 because to find 4 you need ? + 2.5 = 4 and if you take away 4 - 2.5 = 1.5 and that is what the question mark is
To make it it is -3 x ? = 1.5 and there you get -0.5
