1. The sum of two numbers is 137 and
their difference is 43. Find the numbers.
2. The sum of the numerator and denominator of a fraction is 8. If 3 is added to the both numerator and denominator the fraction becomes 3/4. find the fraction.
3. Solve 2x + 5y = 17, 5x + 3y = 14 by
substitution method
4. 10x + 3y = 75 & 6x – 5y = 11 by
substitution method
5. Solve the following equations
graphically. X + 2y = 5, 2x – 3y = -4 and also find the points where these
lines meet the x axis.
