x=-8

Step-by-step explanation


f(x)=-(1)/(2)x+6

Step 1

there is a value for x , that when you replace it inthe equation you obtain 10,then


\begin{gathered} f(x)=-(1)/(2)x+6=10 \\ -(1)/(2)x+6=10 \end{gathered}

Step 2

solve for x


\begin{gathered} \text{isolate x} \\ -(1)/(2)x+6=10 \\ \text{subtract 6 in both sides} \\ -(1)/(2)x+6-6=10-6 \\ -(1)/(2)x=4 \\ \mu ltiply\text{ each side by -2} \\ -(1)/(2)x\cdot-2=4\cdot-2 \\ x=-8 \end{gathered}

so, the answer is x=-8
