a) 3x − 5 = 4

3x = 4 + 5

3x☠ = 9

x = 9 : 3

x = 3

b) 2x 3x-1 x

+ =

3 6 2

4x + 3x-1 = 3x

4x+3x-3x=1

4x =1

x = 1

a=y(x+y)-(x+y)

=(x+y)(y-1)

b=

a) = 4x³y-2

b)= x³-2x²+xy-x²y+2xy-y²−x³
+x²
y

=-2x²+3xy-y²

a) 6x-2=10

6x=10+2

6x=12

x=12:6

x=2

b) (3x)²+2.(3x).4+4²-(3x)²-1²=49

9x²+24x+16-9x²-1=49

24x+16-1=49

24x=49-16+1

24x=34

x=34:24

a) A=5x²y-3x+1
