julia-pushkina [17]
Thhe easiest way would be to solve for y first
4x=3y-7
add 7
4x+7=3y
divide both sides by 3
(4x+7)/3=y

try each
x=4
(4(4)+7)/3=y
(16+7)/3=y
(23)/3=y
7 and 2/3=y
(4,7.66666)


x=5
(4(5)+7)/3=y
(20+7)/3=y
(27)/3=y
9=y
(5,9)

x=6
(4(6)+7)/3=y
(24+7)/3=y
(31)/3=y
10 and 1/3=y
(6,10.333)



(4,7.66666)
(5,9)
(6,10.333)
