# Solve the Following Sets of Simultaneous Equations. 2x - 7y = 7; 3x + Y = 22 - Algebra

Sum

Solve the following sets of simultaneous equations.
2x - 7= 7; 3+ y = 22

#### Solution

2x - 7= 7                              .....(I)
3+ y = 22                            .....(II)
Multiply (II) with 7
21x + 7y = 154                      .....(III)
(I) + (III)
23x = 161
x = 7, y = 1
