Easiest method solving 2 unknowns is Substitution. 
So there will normally be 2(ormore)equations given. 
Say 
X+Y= a
 bX=cY + d 
a b c d are numbers they give
So first we rearrange the first equation
X  = a - Y 
No we substitute this into the 2nd equation so that we can get Y
since we know X = a-Y, 
b(a-Y) = cY + d 
we rearrange and we can find Y for this, it is just Y and numbers
hence finding Y, we sub the value for Y into X = a-Y and we get X also .

What is the ratio a:b if 8a=3b?
Digiron [165]

The ratio a:b is 3:8

Step-by-step explanation:

In simple words, the ratio a:b means the fraction a/b.

So we will have to solve the given equation for a/b

Given

8a=3b

Dividing both sides by 8

\frac{8a}{8}=\frac{3b}{8}\\a=\frac{3b}{8}

Dividing both sides by b

\frac{a}{b}=\frac{3b}{8*b}\\\frac{a}{b} =\frac{3}{8}

The ratio a:b is 3:8
