Solve :
2-9Z17-4Z=45
Given: 2-9Z17-4Z=45
After cross-multiplication, we get;
⇒5(2-9Z)=4(17-4Z)⇒10-45Z=68-16Z⇒10-68=-16Z+45Z⇒-58=29Z⇒Z=-5829⇒Z=-2
Hence,Z=-2 is the correct answer.
2−9z17−4z=45
Simplify and solve the following linear equation:3(5z−7)−2(9z−11)=4(8z−13)−17
The sum of the series 23!+45!+67!+... to ∞ = ae. Find (a+3)2.
