Question

can anyone solve this with calculations please. I need it on Monday, finally Tuesday
a) 5x-9 = 3( x-1)
b) 1,4x+7 = 2,5(x+10)
c) 7(+3) -3(−1) = 5(+3)
d) 5−5 = +315
e) (−1)(+6) - (−2)2 = 2(3+4)

Answer 1

Answer:

Sorry it is too confusing

Step-by-step explanation:

Answer 2

(a) 5x-9=3(x-1)

=5x-9=3x-3

=5x-3x=-3+9

=2x=6

(b) 1,4x+7= 2,5(x+10)

=1,4x+7=2,5x+50

=4x-5x = 2+50-1

= x =52-1

= x = 51

(c) 7(+3)-3(-1) = 5(+3)

= 21 + 3 = 15

= 24= 15

(d) 5-5= +315

=0 = +315

(e) (-1)(+6)-(-2)2 = 2(3+4)

= 6 +4 = 6+8

= 10 = 14

i hope it help u

tak gayi yrr
