Is it possible to find a value for c so that the
linear system below has exactly one solution?
Explain.
5x + 3y = 21 Equation 1
y = -x + c Equation 2

Step-by-step explanation:

Let's solve for c.

y=−x+c

Step 1: Flip the equation.

c−x=y

Step 2: Add x to both sides.

c−x+x=y+x

c=x+y

c=x+y

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380
