Question

Solve the following pair of equation by method of cross multiplication x + 2y = -1 ; 2x + 3y -12 = 0​

Answer 1

Answer:

y is -14 x is 27

Step-by-step explanation:

x+2y+1 =0 }1

2x+3y-12=0 }2

x+2y+1=0

By Mutiplying LHS and RHS by 2

2x+4y+2=0

2x+3y-12=0

(-) (-) (+)

____________

y+14=0

y=-14

x-28+1=0

x=27
