Answer:
x=1
y=0
Step-by-step explanation:
(x-1)=-2x+2
3x-1=2
3x=3
x=1
-2(1)+2
-2+2=0
Answer:
x=-1 , y=-2
Step-by-step explanation:
Replace y in the first equation with x-1.
So, we have -4x+3(x-1)=-2
Multiply brackets with 3: -4x+3x-3=-2
-4x+3x=-2+3 (-3 becomes +3 after it changes sides)
-x=1 /*(-1)
x=-1
After we have x we include it in y=x-1
y=-1-1
y=-2

Answer: $78.19</h3>
Work Shown:
7% of balance = 7% of 1117.00 = 0.07*1117.00 = 78.19
Since 78.19 is larger than 20.00, we go with 78.19 as the minimum monthly payment.
Answer:
(40+ 19) – 38
Step-by-step explanation:
We need to find the expression for "thirty-eight less than the sum of forty and nineteen".
Sum of forty and nineteen = 40 + 19
38 less than the above is 40 + 19 - 38
Overall expression is :
(40 + 19) - 38
Hence, the correct option is (d) "(40+ 19) – 38".
