Question

Solve the equation: 7x=42.

Answer 1

First, we need to see what operation is being applied to 7 and x.
The operation that is being applied is multiplication.

Since the inverse operation of multiplication is division, we have to apply that to both sides of the equation.

7x=42
7x/7=42/7

7 and 7 cross out, and we are left with x on one side of the equation.

x=42/7
x=6

Our final answer is that x=6

Answer 2

To solve this equation, you need to find the value of x. Because you currently have the value of x × 7, you need to divide it by 7 to find the value of x.

7x ÷ 7 = x
Whatever you do to one side of the equation, you must do to the other, so
42 ÷ 7 = 6.

If you divide both sides by 7, you get x = 6 which is the final answer.
