Answer:
3/7
Step-by-step explanation:
9 = 3 + 4 x 7 - 6
Switch the sides
3 + 4x · 7 - 6 = 9
Multiply the numbers
4 x 7 = 28
3 + 28x - 6 = 9
Group like terms
28x + 3 - 6 = 9
Add/Subtract the numbers
3 - 6 = -3
28x - 3 = 9
Add 3 to both sides
28x - 3 + 3 = 9 + 3
Simplify
28x = 12
Divide both sides by 28
28x = 12
28 28
Simplify
x = 3/7
