Answer:
x=5
Step-by-step explanation:
h (x) = 3
We want the x values where y =3
The values are x = -7 and x=5
The equivalent expression of a + 5 is -(-a - 5)
<h3>How to rewrite the expression?</h3>
The expression is given as:
a + 5
Multiply by 1
1 * (a + 5)
Express 1 as -1 * -1
-1 * -1 * (a + 5)
Open the bracket
-1 * (-a - 5)
This gives
-(-a - 5)
Hence, the equivalent expression of a + 5 is -(-a - 5)

Answer:
y=3
Step-by-step explanation:
3x+2y=9
Let x =1
3*1+2y=9
3 +2y = 9
Subtract 3 from each side
3-3+2y=9-3
2y = 6
Divide each side by 2
2y/2 = 6/2
y =3
