First, distribute the coefficients: $0.45x + 18 + 0.25x + 5 = -19$. Combine like terms: $0.7x + 23 = -19$. Subtract 23 from both sides: $0.7x = -42$. Divide by 0.7: $x = -60$.

Solve the Equation 0.45(x+40)+0.25(x+20)=−190.45 ( x + 40 ) + 0.25 ( x + 20 ) = - 190.45(x+40)+0.25(x+20)=−19

Solve the Equation $0.45 ( x + 40 ) + 0.25 ( x + 20 ) = - 19$
