Answer:
x=-21, y=35
Step-by-step explanation:
3x+2y=7 ⇒ 3x+2y=7
y=3-x+11 ⇒ y= -x+14 now we know what y is.
so substitute y for -x+14 and solve the equation:
3x+2(-x+14)=7
3x-2x+28=7
x=-21 so now we know what x is.
Substitute x into y=-x+14 and you get 35, so x=-21, y=35.
Hope this helped!
Answer: The answer is 7.
Step-by-step explanation: Okay. so y = 3 - 3x + 11.
Equation: 3x + 2y = 7
Another way of writing this is:
3x + 2(3 - 3x + 11) which translates to:
3x + 6 - 6x + 22 = 7
Add the numbers together, and you get this:
3x = 21
Divide 21 by 3, and you get:
x = 7
