Answer:
x = 3 or y = -3
Step-by-step explanation:
To find x, substitute y with a 0.
0=x-3. Minus the x on both sides and x will equal 3
To find y, substitute x with a 0.
y=0-3. 0-3 equals -3 which means that y will equal -3
You want the xs and the numbers on different sides.
2x-3x=-11-4
-x=-15
divide x by a -1
x=15
The decimal equivalent of 1/4 is 0.25.
