Answer:
x= -7, y= 12
Step-by-step explanation:
To find the value of x and y, first label the 2 equations.
2x +y= -2 -----(1)
x +y= 5 -----(2)
(1) -(2):
2x +y -(x +y)= -2 -5
2x +y -x -y= -7 <em>(</em><em>expand</em><em> </em><em>bracket</em><em>)</em>
x= -7
subst. x= -7 into (2):
-7 +y= 5
y= 5 +7 <em>(</em><em>+</em><em>7</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>
y= 12

Answer:
She will spend over 10 pounds on candy.
Step-by-step explanation:
You have to multiply 6(the amount of money for each candy) with whatever number equals 60(the total she will spend) which is 10(the amount of pounds she is buying) so she will spend more than 10 pounds.
Ex.
6×10=60
C . 4
3+2+7=12
12 divided by 3 equals 4.
