Question

Solve the equation 14x + 7y= 28 for x.

Answer 1

Answer: x=
`(28-7y)/(14)`

Step by step explanation: 14x+7y=28, an equation where no variable represents a number is kind of tricky but since we are solving for x, it is simple. X must stand alone since it has become the subject. Wedivide both sides by 14 to make the x stand alone. So, it becomes 14x÷14 which will obviously give you 1x but in math, we do not write 1x; the one is invisible. Then the 14 will divide 28-7y. It then becomes,
`(28-7y)/(14)`. To verify whether the answer is correct, try sending everything back to its normal position, which means multiply both sides by 14 to make 28-7y free and to check whether it will take you back to the question. And it does. So, x=
`(28-7y)/(14)`.
