Question

Solve:x-2y=-7 and 4x+3y=5​

Answer 1

Answer:

x = -1

y = 3

Step-by-step explanation:

x-2y= -7 ( 1st EQUATION)

4x+3y=5( 2nd EQUATION)

SO,

IN FIRST EQUATION,

x-2y= -7

y = (x+7)/2

NOW,

SUBSTITUTING THE VALUE OF y IN EQUATION 2

WE GET,

4x+3y=5

4x+3[(x+7)/2] = 5

(8x+3x+21)/2 = 5

11x+21=10

11x=-11

x= -1

y=3
