Step-by-step explanation:
HERE,
two equation are,
●-4x+9y=14••••••••••••(equation I)
●12x-10y=-8•••••••••••(equation II)
First multiplying 3 in equation I
we get,
=
••(equation III)
Then,
we combine the equationii and equation III.
we get that,
Then,
put the value of y in equation II.
WE get,
So,
solution of the two equation (-4x+9y) and (12x-10y=-8) is (1,2)

Step-by-step explanation:
Step 1: Define Systems
-4x + 9y = 14
12x – 10y = -8
Step 2: Rewrite Systems
-4x + 9y = 14
Step 3: Redefine Systems
-12x + 27y = 42
12x – 10y = -8
Step 4: Solve for y
Elimination
Step 5: Solve for x
