Answer:
Step-by-step explanation:
x + 2y = 8 -----------(I)
x - 2y = -4 -----------(II)
Add equation (I) & (II) and thus y will be eliminated and we can get the value of 'x'
(I) x + 2y = 8
(II) <u>x - 2y = -4</u><u> </u>{Now add}
2x = 4
x = 4/2
x = 2
Substitute x = 2 in equation (I)
2 + 2y = 8
2y = 8 - 2
2y = 6
y = 6/2
y = 3
Equation - 7.60b+60=m
7.60b+60=100
