(c)9y= –135
ans- –15

(d)15–x=4
ans-11

(e)3(x–3)=15
ans-8

(f)7y+3=9
ans-6/7​

Answer 1

Step-by-step explanation:

Solutions

a) x+7=9

= x=9-7

:• x=2 @

b) x/4=25

= x=25×4

:• x=100 @

c) 9y= –135

= y= -135 -9

:• y= -15 @

(d) 15–x=4

= 15-4=x

= 11=x

:• x=11 @

(e) 3(x–3)=15

= 3×(x-3)=15

= 3x-9=15

= 3x = 15-9

= 3x = 6

= x = 6/3

:• x = 2 @

(f)7y+3=9

= 7y=9-3

= 7y=6

= y = 6/-7

:• y = -6/7 @
