Answer:

3x+2y=36 Subtracting 3x from both sides and then dividing both sides by 2 gives us: y=18-1.5x We then substitute this into the second equation, in place of y. Giving us: 5x+4(18-1.5x)=64 Multiplying out of the brackets gives us.

Answer:

x = 8, y = 6

Step-by-step explanation:

3x + 2y = 36 (1)

5x + 4y = 64​ (2)

1 x 2:

6x + 4y = 72 (3)

(3) - (2) :

x = 8

Substituting x=8 in (1):

24 + 2y = 36

2y = 12

y = 6
