Answer:

Step-by-step explanation:

a = adult cost

c = child cost

a = c + $3

200a + 100c =$2100

^ each # of tickets sold

200(c+3) + 100c =$2100

200c + 600 + 100 c = 2100 combine like terms

300c + 600 = 2100 need variable only on one side of equal sign so you subtract 600 from each side of the = sign

300c = 1500 now divide by 300 on both sides to isolate variable

c = $5

The letters a,b and c, represent nonzero constants. Solve ax+b=c for x

insens350 [35]

Answer:

$x = \frac{c-b}{a}$

Step-by-step explanation:

To solve for x, x needs to be on one side while all the other variables are on the other

To do this first subtract b from each side making the equation,

ax = c - b

Now divide by a on both sides. This means that to solve for x the equation must be ...

$x = \frac{c-b}{a}$
