Question

Solve. 4 + x/7 = 2Question 3 options:12-144210

Answer 1

`x=-14`

1) Since we have a Rational Equation let's proceed with that, isolating the x on one side and then we can get rid of that fraction. This way:

`\begin{gathered} 4+(x)/(7)=2 \\ 4-4+(x)/(7)=2-4 \\ (x)/(7)=-2 \end{gathered}`

Notice that now, we're going to get rid of that fraction on the left side, multiplying it by 7 (both sides) :

`\begin{gathered} 7*(x)/(7)=-2*7 \\ x=-14 \end{gathered}`

Thus, the answer is -14
