merupakan penyelesaian dari sistem persamaan 2x + 3y - 5 = 0 dan 2x = 1+3y nilai 4x + 3y =

2x +3 y -5 =0
2x +3y = 5

2x = 1+3y
2x - 3 y = 1

2x + 3y = 5
2x - 3y = 1
______________ _
0 + 6 y = 4
y = 4/6
y = 2/3

2x +3 y = 5
2x + 3(2/3) = 5
2x + 2 = 5
2x = 5 - 2
2x = 3
x = 3/2

4x + 3 y = 4(3/2) + 3(2/3)
= 6 + 2
= 8
