Question

Solve the simultaneous equation 2x+y=8, y=1+x/2 graphically

Answer 1

Answer:

solution box

x|1,2,3=

y|6,4

x=1 then now,

2(1)+y=8

2+y=8

y=8-2

y=6

then y=6

2(2)+y=8

4+y=8

y=8-4

y=4

then y= 4

2(3)+y=8

6+y=8

y=8-6

y=2

then y=2

SOLUTION BOX

X=1,2,3

Y=6,4,2

XY,1×6,2×4,3×2
