X +y=5, 3x-2y+5=0, this is the question​
Neko [114]

Step-by-step explanation:

x+y=5

3x-2y+5=0

3x-2y= -5

x+y=5...... equation 1

3x-2y= -5....... equation 2

there fore make x the subject of the formula in equation 1

x=5-y.. equation 3

substitute equation three in equation 2

3(5-y)-2y=-5

15y-3y-2y=-5

10y=-5

divide both sides by 10

y=-5/10

y=-½

substitute y into equation 1

x+(-½)=5

x=5+½

x=5½

x=5½,y= -½
