Answer:
combine -3-1

if you want to solve for x then you would move the -14 to the left buy adding 14 to both sides.

your equation there will be

then you will divide -2 on both sides

finally x will equal

4) a. x+y=1–(1)
y=2x-8—(2)
(2) into (1)
x+(2x-8)=1
3x-8=1
3x=1+8
x=9/3
x=3—(3)
(3) into (2)
y=2(3)-8
y=-2
ans x=3, y=-2
b. x+y=19—(1)
y=5x+1—(2)
(2) into (1)
x+(5x+1)=19
6x+1=19
6x=19-1
x=18/6
x=3—(3)
(3) into (2)
y=5(3)+1
y=16
ans x=3, y=16
c.x+y=-2—(1)
y=x-10—(2)
(2) into (1)
x+(x-10)=-2
2x-10=-2
2x=-2+10
x=8/2
x=4–(3)
(3) into (2)
y=4-10
y=-6
ans x=4, y=-6
5) 3x=y—(1)
x=y-16–(2)
(2) into (1)
3(y-16)=y
3y-48=y
2y=48
y=48/2
y=24–(3)
(3) into (2)
x=24-16
x=8
ans x=8, y=24
<h2>
The "option d:
+ 13x + 12" is a trinomial with a constant term.</h2>
Step-by-step explanation:
To check options:
a: x + 4y
Here, the coefficient of x = 1 and the coefficient of y = 4
b: 
Here, the coefficient of
= 1
c:
+ 3
+ 2y
Here, the coefficient of
= 1, the coefficient of
= 4 and the coefficient of y = 2
d:
+ 13x + 12
Here, the coefficient of
= 1, the coefficient of x = 13 and
constant term = 12
Thus, the "option d)
+ 13x + 12" is a trinomial with a constant term.
I think it might be 45a+5?
