Answer:
x = −1/13 and y = 33/13 or 2 7/13
Step-by-step explanation:
x+2y=5
x+2(6x+3)=5
x+12x+6=5
13x+6=5
-6 -6
13x= -1
/13 /13
<u>x= -1/13</u>
y=6x+3
y=6(-1/13)+3
y= 33/13
y= 2 7/13
I think you multiply rong
Answer:
A) D + Q = 50
B) .10D + .25Q = 7.10
We multiply A) by -.10
A) -.10D - .10Q = -5 then adding this to B)
B) .10D + .25Q = 7.10
.15Q = 2.10
Quarters = 14 = 3.50
Dimes = 36 = 3.60
