Answer:
x = -7
Step-by-step explanation:
4x-9 = 7x+12
Add 9 to both sides
4x = 7x + 21
Subtract 7x from both sides to further isolate the variable
-3x = 21
Divide both sides by -3
x = -7
Plug the value in to check your work:
4(-7) - 9 ? 7(-7) +12
-28 - 9 ? -49 + 12
-37 ? -37
-37 = -37
Answer: y=17
Explanation:
Notice that every time x decreases by 2, y increases by 8, and every time x decreases by 1, y increases by 4. That mean when x = 0, y = 5+4+4+4=17
