First, distribute the -0.7: $0.5x + 1 = 5 - 0.7x + 1.4$. Simplify to $0.5x + 1 = 6.4 - 0.7x$. Add $0.7x$ to both sides: $1.2x + 1 = 6.4$. Subtract 1 from both sides: $1.2x = 5.4$. Divide by 1.2: $x = 4.5$.

Solve 0.5x+1=5−0.7(x−2)0.5 x + 1 = 5 - 0.7 ( x - 2 )0.5x+1=5−0.7(x−2)

Solve $0.5 x + 1 = 5 - 0.7 ( x - 2 )$
