X is six more than four times the value of y.
2 answers:
Therefore (4y+6) +y = 46 We can combine the like terms: 5y + 6 = 46 Subtract 6 on both sides: 5y+6-6=46-6 Therefore 5y =40 Divide by 5 on both sides 5y/5 = 40/5 Therefore y= 8 We found y but to find the value x we use y. X= 4y+6 Therefore x= (4*8)+ 6 Therefore x= 32 + 6 x= 38.
X + y = 46
x is six more than four times the value of y
so replace x with that
6+4y + y = 46
add
4y+y=5y
so
6+5y=46
subtract 6 from both sides to remove the 6 in the left.
5y = 40
Divide both sides by 5, the coefficient of y. 5y/5=y and 40/5=8

Answer:
area is 84
Step-by-step explanation:
perimeter is 38(p)
length (l) is 7cm
width is?(w)
p=2(l+w)
38=2(7+w)
38=14+2w
2w=38-14
2w=24
w=12
area=l*w
12*7
=84
First, divide.
680 / 4 = $170 per TV
Second, multiply.
170 * 7 = $1,190
