Step-by-step explanation:
Answer: multiply the other side by 3 also
Step-by-step explanation:
What happens to one side must also happen to the other side. This is the only way to keep equations equal when changing constants and variables
Answer:
length = 16m
width = 4m
Step-by-step explanation:
1. if the length is 4 times the size of the width then we can call the width x and the length is 4x
2. make an equation 4x + 4x + x + x = 40m
3. solve the equation 10x = 40 x = 4
4. width = x width = 4m length = 4x length = 16m
5. check this 16 + 16 + 4 + 4 = 40
Answer:
3
Step-by-step explanation:
Move the terms : 2x + 1 =10 -x
Collect like terms
Calculate : 2x + x=10-1
Divide both sides
3x = 9
x = 3
