Solve 4x+3y=65 and x+2y=35​

Answer»

Step-by-step explanation:

4x+3y=65 ----> (1)

x+2y=35 -----> (2)

In eq (2), x= 35-2Y ----> (3) Put in eq (1)

4(35-2y) +2y= 65

140 - 8y + 2y = 65

-6y = 65-140

y = -75/-6

Therefore, y= 12.5 Put in eq (2)

Now, x+2y=35

=> x + 2(12.5) =35

=> x = 35- 24

=> x= 11

Therefore, x=11 and y=12.5
