This would equal -1.44. Hope this helps!
The system of equations are:
2x − 4y = 6
−3x + 3y = 9
To eliminate x, you should:
1. multiply first equation with 3
2. multiply second equation with 2
3. add the new equations you got
So your answer is A.
Answer:
£168
Step-by-step explanation:
To increase £120 by 40%, multiply 120 by 1.4
120(1.4)

Y= 0.8x - 17
x= (y+17)/0.8
substituting y= 47 in the equation
x= (47+17)/0.8
x= 64/0.8
x=80
