Answer

$v_1=\frac{2s}{t}-v_2$

Work Step by Step

Multiply $2$ to both sides of the equation: $2(s)=2 \cdot \frac{(v_1+v_2)t}{2} \\2s= (v_1+v_2)t$ Divide $t$ to both sides of the equation: $\frac{2s}{t} = \frac{(v_1+v_2)t}{t} \\\frac{2s}{t}=v_1+v_2$ Subtract $v_2$ to both sides of the equation: $\frac{2s}{t}-v_2=v_1+v_2-v_2 \\\frac{2s}{t}-v_2=v_1$
