Analyze Equation: Analyze the first equation in the system.The first equation is −10.74=u−(−11). This can be simplified by removing the double negative on the right side of the equation.
Simplify Equation: Simplify the equation by adding 11 to both sides.−10.74=u−(−11) becomes −10.74=u+11.
Subtract to Solve: Subtract 11 from both sides to solve for u. −10.74−11=u+11−11 This simplifies to −21.74=u.
Check Solution: Check the solution by substituting the value of u back into the original equation.−10.74=−21.74−(−11)−10.74=−21.74+11−10.74=−10.74The left side equals the right side, so the solution is correct.
