Let's tackle each equation one by one! For equation (a) \( -4(y+1)+6 y=2(y+2)-8 \): First, simplify both sides: LHS: \( -4y - 4 + 6y = 2y - 4 \); RHS: \( 2y + 4 - 8 = 2y - 4 \). Now, we have \( 2y - 4 = 2y - 4 \). Since both sides are identical, this means all real numbers are solutions! For equation (b) \( 6(u-2)+1=2(3u-5) \): Expanding both sides yields: LHS: \( 6u - 12 + 1 = 6u - 11 \); RHS: \( 6u - 10 \). Now, setting them equal gives \( 6u - 11 = 6u - 10 \). This simplifies to \( -11 = -10 \), which is a contradiction, meaning there is no solution! To summarize: (a) All real numbers are solutions. (b) No solution.
