Answer:
<h3>x = -30</h3>
Step-by-step explanation:
minus 12 on both sides
updated equation: x/3=-10

updated equation
x = -30
Answer:
see explanation
Step-by-step explanation:
(i)
+
= 1 ( multiply through by 6 to clear the fractions )
2x + 3y = 6 ( subtract 2x from both sides )
3y = - 2x + 6 ( divide through by 3 )
y = -
x + 2
(ii)
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope ( gradient ) and c the y- intercept )
y = -
x + 2 ← is in slope- intercept form ( that is part (i)
with gradient m = -
