Important question in 1st year engineering in second sum lingar Algebra
If x = 4, y = 5 so find the value of z from the following equation x+y-z = 5
1. What is Algebra? Algebra is a branch of Mathematics that uses letters and symbols to represent numbers and quantities in formulas and equations. These letters are called variables and they help us solve problems where some values are unknown. Example:If +5=10x+5=10, we can find the value of x by subtracting 5 from both sides.So, […]
2-36(114+25)=2-36(139)=2-5004=-5002
The value of x in this equation ( 2x+6=0) is -3.
