HEY can someone PLEASE help me and show how you got the answer quick i’m in an exam

ok so first you gotta find y

first step

7y+3+3y-5=9y+7

second step (part a)

10y+3-5=9y+7

second step (part b)

10y-2=9y+7 (since there was negative 5 and 5 was bigger our answer will be in negative)

third step

10y-9y=7+2

fourth step (part a)

1y=7+2

fourth step (part b)

1y=9

fifth step

y=9

ok now tht u got the y

the second part will be ez

now i will be doing b

GI=9× 9+7

81+7

88

Step-by-step explanation:

explanation for the first step: since GH+HI=GI our equation will be 7y+3+3y-5=9y+7

explanation for the second step( part a)

add all the numbers which has y with one another

explanation for the second step (part b)

add all the numbers which are without the y

( do not do the one after the equal sign (=) )

explanation for the third step

we move all the y in one side ( with their number ofc)

and all the numbers without y to the other

(obv the sign changes when u move them)

explanation for the fourth step (part a)

we add them ( all the y together)

explanation for the fourth step (part b)

we add them ( all the number without y)

explanation for the fifth step

we remove 1 cz 1y=y

now i will be doing b

explanation for the first step (for q b)

since y=9

we will replace y with 9

explanation for the second step (for q b)

as the rule of math we will do the multiplication first

and 9× 9=81

explanation for the third step

add 81 and 7

a) y= 9

b) GI= 88

hope this help and hope I explained everything
