X^2 +3x-4=0
(X+4)(x-1)=0 so x = -4 and x=1 are solutions

OK, so judging from the bar shown : </h3>
It looks like <u>Rent</u> takes up 1/3 of the space so 33.33..%
It also looks like <u>Loan Repayment</u> + <u>Savings</u> is another 33.33..% but Savings is slightly larger than Loan Repayment so you could just estimate Savings to be 55% and LR to be 45% of the 1/3 space. 
LR looks equal to <u>Entertainment</u> making it another <u>14.99.</u>
It also looks like Entertainment + Electricity + Groceries = the last 33.33..%
And since we know <u>Entertainment</u> = 14.99 / 45% of 33.33..
Making <u>Electricity and Water</u> <em>ABOUT</em>  35% of 33.33... which is <u>11.66</u>
And Groceries is somehow 20% of 33.33 = <u>6.66</u>
- Rent = 33.33..%
- Savings = 18.33%
- Loan Repayment 14.99%
- Entertainment 14.99%
- Electricity and Water 11.66%
- Groceries = 6.66%
<h3>
All of these added together equal <u><em>
ABOUT</em></u>
 100%</h3>
