Answer: w = -3/2u + 2
Step-by-step explanation: The independent variable, normally x, is not impacted by other variables. The problem is asking you to put the equation in w= form. W is the dependent variable while u is the independent variable (we’re used to seeing y= form, where x is independent and y is dependent. This is the same thing with different letters).
-12u + 13 = 8w - 3
-12u + 16 = 8w (add 3 to both sides)
(-12u + 16)/8 = w (divide both sides by 8)
-12/8u + 16/8 = w
-3/2u + 2 = w (simplify)
