Question

0.4x + 3y = 2.6
x - 2y = 4.6

Answer 1

Step-by-step explanation:

0.4x+3y=2.6

Multiply both sides by 5

5(0.4x+3y)=5(2.6)

2x+15y=13___(1)

x-2y=4.6

Multiply both sides by 2

2(x-2y)=2(4.6)

2x-4y=9.2____(2)

(1)-(2)=> 19y=13-9.2

19y=3.8

y=0.2

x-2y=4.6

x-2(0.2)=4.6

x-0.4=4.6

x=4.6+0.4

x=5
