Question

please give correct answer please​

Answer 1

Answer:

( a ) x+5=10

=x =10-5=5

(b) x+10=6

= x = 6-10= -4

(c) 2x-7=35

= 2x = 35+7= 42

= x= 42÷2

= x= 21

(d) 4x -20= -20

= 4x = -20+20

= 4x = 0

= x = 0÷4=0

(e) 5x-16= -30

= 5x = -30+16

= 5x = -14

= x = -14/5

Answer 2

answer :-

a}. x = 5

b}. x = -4

c}. r = 21

d}. x = 0

e}. x = -2.8

Step-by-step explanation:

a}. x + 5 = 10

= x = 10-5

= x = 5

b}. x + 10 = 6

= x = 6-10

= x = -4

c}. 2r - 7 = 35

= 2r = 35 + 7

= 2r = 42

= r = 42÷2

= r = 21

d}. 4x-20 = -20

= 4x = -20+20

= 4x= 0

= x= 0÷4

= x= 0

e}. 5x - 16 = -30

= 5x = -30+16

= 5x = -14

= x = -14÷5

= x = -2.8
