Answer:
Step-by-step explanation:
a) 3x+2(41-5x)=33 as y=41-5x is given
3x+82-10x=33
-7x+82=33
-7x=33-82
-7x=-49 cut the negative signs as its LHS and RHS
<u>x=49/7=7</u>
b)-5x+3(3x-3)=3 as y=3x-3 is given
-5x+9x-9=3
4x-9=3
4x=3+9
<u>x=12/4=3</u>
<u>c</u>)4x+11-5x=9
-x+11=9
-x=9-11
-x=-2 cut the negative signs as its LHS and RHS
<u>x=2</u>
d) 5y+ -5-2y=-11 as x=-5-2y is given
3y+-5=-11
3y=-11+5
3y=-6
<u>y=-6/3=-2</u>
e)-5x-4(2x+1)=35 as y=2x+1
-5x-8x+4=35
3x+4=35
3x=35-4
3x=31
x=31/3
<u>x=10.3</u>

Answer:
x=3
Step-by-step explanation:
If k is between J and L, then
JK + KL = JL
2x+11 + (3x) = 13x-13
Combine like terms
5x +11 = 13x -13
Subtract 5x from each side
5x-5x+11 = 13x-5x-13
11 = 8x-13
Add 13 to each side
11+13 = 8x-13+13
24 = 8x
Divide by 8
24/8 = 8x/8
3 =x
