Y decreased by 23 is 52.9....
y - 23 = 52.9 <== ur equation
y = 52.9 + 23
y = 75.9
================
c - 12 = 6 <== ur equation
c = 6 + 12
c = 18
================
h - 234 = 1192
h = 1192 + 234
h = 1426
no, he is not correct because he did not add 234 and 1192 to find the value of h, which is 1426

x

inverse means

1

variable

To convert to an equation introduce k, the constant of variation.

y

=

k

1

x

⇒

y

=

2y-18x=-26 solve for y
Alekssandra [29.7K]
2y - 18x = -26

Add 18x to both sides.

2y = -26 + 18x

Divide by 2 on both sides.

y = -13 + 9x

y = 9x - 13
