Question

4x+3y=5

Answer 1

We will solve the system of equations:
4 x + 3 y = 5
2 x - 5 y = - 17   /  * ( - 2 )    / We will multiply both sides of an equation by - 2.
----------------------------------
   4 x + 3 y  =  5
+
- 4 x + 10 y = 34
-------------------------
           13 y = 39
y = 39 : 13
y = 3
4 x + 3 * 3 = 5
4 x + 9 = 5
4 x = 5 - 9
4 x = - 4
x = - 4 : 4
x = - 1
Answer:  x = - 1,  y = 3.
