Question

6. Use the bar diagram to help you solve the equation 4x - 12 = 16.
​

Answer 1

1. 4x=16+12

2. 4x=28

3. 4x over 4=28 over 4

4. 4 is cancelled by 4 and x will remainder =7

5. x=7

that's it good luck

Answer 2

4x - 12 = 16

adding 12 to both side

4x - 12 + 12 = 16 + 12

4x = 28

devide both side by 4

4x ÷4 = 28÷4

x = 7
