Question

solve the following pair of linear equation by the subsitute method -
1 2x + 3y=46
3x+5y=74​

Answer 1

Answer:

x= 0.16 y= 14.7

Step-by-step explanation:

multiplying eq2 by 4

12x+ 3y=46

12x+ 20y= 296

deducting bottom eqn from top we get 17y =250 so y= 14.7

putting in second eqn we get 3x+ 73.5 = 74 so x = 0.5/3 = 0.16
