Answer:
4-6w=16 is w=-2
-9-5r=-19 is r=2
5k-7=3k+3 is k=5
Answers:
• w = -2
• r = 2
• k = 5
Explanation:
• Problem #1
Step 1 - Subtract four from both sides of the equation
4 - 6w = 16
4 - 4 - 6w = 16 - 4
-6w = 12
Step 2 - Divide both sides of the equation by negative six
-6w = 12
-6w/ -6 = 12/ -6
w = -2
• Problem #2
Step 1 - Add nine to both sides of the equation
-9 - 5r = -19
-9 + 9 - 5r = -19 + 9
-5r = -10
Step 2 - Divide both sides of the equation by negative five
-5r = -10
-5r/ -5 = -10/ -5
r = 2
• Problem #3
Step 1 - Add seven to both sides of the equation
5k - 7 = 3k + 3
5k - 7 + 7 = 3k + 3 + 7
5k = 3k + 10
Step 2 - Subtract 3k from both sides
5k = 3k + 10
5k - 3k = 3k - 3k + 10
2k = 10
Step 3 - Divide both sides of the equation by 2
2k = 10
2k/ 2 = 10/ 2
k = 5
