The answer to your question is (1,7)
1) solve for x by multiplying each equation with the opposite number and making one a negative
-4(5x + 2y =-9)-4
5(4x +3y = 25)5
2) multiply on both sides of equal sign
-20x - 8y = 36
20x + 15y = 125
3) add all the like terms to get new equation
7y = 161
4) simplify
7y = 161
/7 /7
y = 23
5) make ordered pair and then input 23 into original equation
( x , 23)
5x + 2y = -9
5x + 2(23) = -9
5x + 46 = -9
-46 -46
5x = -55
/5 /5
x = -11
6) input to ordered pair
(-11, 23)
7) Thats your answer!
