Quizplus · Accepted Answer

The equation can be rewritten as $2^{7-3x} = 2^{-2}$. Equating the exponents gives $7 - 3x = -2$. Solving for $x$ gives $x = 3$.

Solve the Equation 2(7−3x)=142 ^ { ( 7 - 3 x ) } = \frac { 1 } { 4 }2(7−3x)=41​

Solve the Equation $2 ^ { ( 7 - 3 x ) } = \frac { 1 } { 4 }$
