Question

B.5(2-x)-(x+3)=11-x C.6(3x-2)+5(x-4)-7x=0 D.2(2y-11)=26 F.4(2y-3)+6(3-y)=22 tolong bantu

Answer 1

B.
5(2-x) -(x+3) = 11- x
10 -5x - x - 3 = 11 - x
-6x + 7 = 11 - x
-6x + x = 11 - 7
-5x = 4
x = - 4/5

c.
6(x-2)+ 5(x-4) - 7x = 0
6x -12 + 5x - 20 - 7x = 0
6x+5x-7x = 12 + 20
6x = 32
x = 32/6x = 16/3

d.
2(2y-11) = 26
4y - 22 = 26
4y = 26 + 22
4y = 48
y = 12

f. 
4(2y-3) + 6(3-y) = 22
8y- 12 + 18 - 6y = 22
8y - 6y + 6 = 22
2y = 22-6 
2y = 16
y = 8

Answer 2

B.5(2-x)-(x+3)=11-x
10-5x-x-3=11-x
-6x+x=11-7
-5x=4
x=-4/5


C.6(3x-2)+5(x-4)-7x=0
18x-12+5x-20-7x=0
16x=32
x=2


D.2(2y-11)=26
4y-22=26
4y=26+22
4y=48
y=12

F.4(2y-3)+6(3-y)=22
8y-12+18-6y=22
2y=22-6
2y=16
y=8
