Question

solve the equation by substitution method 2x + 5 is equals to 1 '2 X + 3 Y is equals to 2​

Answer 1

Step-by-step explanation:

2x+5y=1 ______ i

2x+3y=2

x=(2 -3y)/2 ______ii

putting value of x from eqn ii in eqn i , we have

• 2(2-3y)/2 + 5y=1
• 2-3y+5y = 1
• 2y=-1
• y=-1/2

again substituting the value of y in eqn ii we get

• x=(2-3×1/2)/2
• =(4-3)/4
• =1/4
