Question

Solve for z: mula1" title="\frac{2z-3}{20} - \frac{z-6}{4} = 3" alt="\frac{2z-3}{20} - \frac{z-6}{4} = 3" align="absmiddle" class="latex-formula">

Answer 1

Multiply both sides of the equation by 20. 2z-3-5(z-6)=60. 2z-3-5z+30=60. -3z-3+30=60. -3z+27=60. -3z=60-27. -3z=33. Divide both sides by 3. Answer is: Z= -11
