Answer:
a = - 3 and b = 4
Step-by-step explanation:
Given

Simplify 
=
=
×
= 3
Thus expression can be written as

Multiply numerator/denominator by 
noting that
×
= 2
= 
= 
Dividing each term on the numerator by 2
= 4
- 3
= - 3 + 4
with a = - 3 and b = 4
<span>1/2x+3y/4=5 => (1/2)x + (3/4)y = 5
1/5x+3y/2=2 => (1/5)x + (3/2)y = 2
Eliminate the fractional coefficients: Mult. the first equation by 4 and mult. the second equation by 10:
2x + 15y = 20
</span><span>Multiply the 1st equation by -1:
-</span>2x - 3y = -20
2x + 15y = 20
-------------------
12y = 0, so y = 0. Then the first equation becomes 2x + 3(0) = 20, or
x=10.
Solution is (10,0).
in simplist form it should be 3x+16
