11) 2x+6y-3; x=5,y=4
the question is asking to evaluate for y when x=5 and evaluate for x when y=4,
2x+6y-3
2x+6y=3
2(5)+6y=3
10+6y=3
6y=3-10
y=-7/6 when x=5
2x+6(4)=3
2x+24=3
2x=3-24
x=-21/2 when y=4
12)
Input Output
N 4(n+3)
12 4(12+3) = 4(15)=60
14 4(14+3)=4(17)=68
18 4(18+3)=4(21)=84
25 4(25+3)=4(28)=112
13)8x+y-10; x=4, y=50
8x+y=10
8(4)+y=10
32+y=10
y=10-32
y=-22 when x=4
8x+50=10
8x=10-50
8x=-40
x=-40/8
×=-5/1=-5 when y=50

If you would like to know how many sixths are in 4, you can calculate this using the following steps:
n ... the number of sixths
n * 1/6 = 4
n = 4 * 6
n = 24
The correct result would be: 24 sixths are in 4.
W(x) = 4x + 5
w(-8) = 4(-8) + 5 = -32 + 5 = -27
Answer:
-4
Step-by-step explanation: if the signs are different subtract the values and take the sign of the larger number!
