A) Solve 3x+6y=24 for x.
Subtracting 6y from both sides, we get
3x+6y-6y=24-6y
3x = -6y+24
Dividing both sides by 3, we get
x= -2y + 8
b) Solve 24−3x=6y for x.
Subtracting 24 from both sides, we get
24-24−3x=6y-24
-3x = 6y -24.
Dividing both sides by -3, we get
x= -2y + 8.
c) Solve 6y=24−3x for y in terms of x.
Dividing both side by 6.
y=
d) Solve 24−6y=3x for x in terms of y.
Dividing both sides by 3, we get
8 - 2y = x.
x = -2y +8
<h3>Therefore, x=-2x+8 andTo solve the given system of equations for substitution you:
1. Solve in one of the equations a variable.
For the given options the one that is correct is solve the first equation for y, by adding x to both sides:
