Question

Write an equation that you could solve using these steps:

Add 7 to both sides. Then, divide both sides by 4.

Explain how you know your answer is right.

Answer 1

Do the opposite of the given operations to find the equation.
Let x be a variable.
Multiply it by 4.
u get 4x.
subtract 7 from it.
u get 4x-7.
Equate it to zero to get the eqn.
4x-7=0
add 7 to both sides
4x-7+7=0+7
4x=7
divide both sides by 4
4x/4=7/4
x=7/4
