Question

*Assignment no.3*

*Solve the following simultaneous equations.*
1. 2x - 3y = 26 ; 2x + y =13 ​

Answer 1

Answer:

-65/4

Step-by-step explanation:

Here you go with step by step solution

2x-3y=26 ---- 1

2x+y=13 ------2

From 2

y=13-2x -----3

put

3 in 1

We get

2x-3(13-2x)=26

2x-39-6x=26

-4x-39=26

-4x=26+39

-4x= 65

-x=65/4

which gives us

x=-65/4
