X-20 = y+20<br>2Y - 44 = X + 22<br>

nordsb [41]

X-20 = Y+20........ X-Y = 20+20........

X-Y = 40

AND

2Y-44=X+22............. Y-X= 44+22

Y-X=66

NOW, LET'S FIND X AND Y FROM THESE TWO EQUATIONS....

X-Y =40

Y-X= 66

IF WE COLLECT ....... 2Y = 106 AND Y = 53

THEN, USE Y IN ANY EQUATIONS FOR FINDING X

X-53 = 40 ..... X= 53+40 .......... X= 93

X= 93

Y=53
