Respuesta :
wait is it a system of equation or you just want the expression of X and Y
y = 2x + 48
-1 (y = 9x + 13)
---------------------
y = 2x + 48
-y = -9x -13
-------------------
0 = -7x + 35
+7x = +7x
--------------------
7x = 35
x = 5
y = 2x + 48
y = 2(5) + 48
y = 10 + 48
y = 58
x is 5
y is 58
-1 (y = 9x + 13)
---------------------
y = 2x + 48
-y = -9x -13
-------------------
0 = -7x + 35
+7x = +7x

x = 5
y = 2x + 48
