Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
3x + 2 = 17
<u>Step 2: Solve for </u><em><u>x</u></em>
- [Subtraction Property of Equality] Subtract 2 on both sides: 3x = 15
- [Division Property of Equality] Divide 3 on both sides: x = 5
Isolate the s. Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS.
Subtract 19 from both sides
7 (-19) = 4s + 19 (-19)
7 - 19 = 4s
-12 = 4s
Isolate the s. Divide 4 from both sides
-12/4 = 4s/4
s = -12/4
s = -3
-3 is your answer for s

Answer:
not sure if this is what it wants.
Step-by-step explanation:
Answer:
1200 shirts were sold.
400 pants were sold.
Step-by-step explanation:
The ratio of shirts to pants sold = 3:1 (difference of 2)
800 ÷ 2 = 400
Ratio x 400 = 1200:400 (difference of 800)
