Answer:
x = -24
a = 11
Step-by-step explanation:
So for the first one:
[tex]-\frac{1}{4} x+6=\frac{2}{3} x+28[/tex]
Multiply both sides of the equation by 12
[tex]-3x+72=8x+336[/tex]
Subtract 8x from both sides
[tex]-11x+72=336[/tex]
Subtract 72 from both sides
[tex]-11x=264[/tex]
Divide both sides by -11
[tex]x=-24[/tex]
And the second one...
[tex]2(a-2)=3(a-5)[/tex]
Distribute the 2 to the (a - 2) and the 3 to (a - 5)
[tex]2a-4=3a-15[/tex]
then add 15 to both sides
[tex]2a+11=3a[/tex]
Subtract 2a from both sides
11 = a
