40 + 9 = 5y + 9
Since 9 is present on both sides of the equation,therefore we can strike it off on both sides,the remaining equation being 40 = 5y or 5y = 40
5y = 40
or y = 40/5
Therefore,y = 9 .

5y = 2y+9 5y-2y = 9 3y = 9 y = 3
(2, 1)
y=4
18y+48+5y+15 = 270 18y+5y = 270-48-15 23y = 207 y = 9
Can you help with this equation? Thanks. Solve for x and y and z for the following. x plus y plus z equals 9 x plus 2y plus 3z equals 23 x plus 5y plus -3z equals -7
