Solve the following equations and check the solution in each case: (c) y/12=7 (c)4m+32.4=-7:6 (d) 5x-9=3x+7 (e) 5(2x+3)=4(x+1)+2 (b) 3x-3/4=6 (f) y/2-1/2=y/3+1/4

Step-by-step explanation:
c) y/12=7
=> y= 12×7
=> y= 84
CHECK
y/12=7
=>84/12=7
=>7=7
d) 5x-9=3x+7
=> 5x-3x= 9+7
=> 2x= 16
=> x= 16/2
=> x= 8
CHECK
5x-9=3x+7
=> (5×8)-9=(3×8)+7
=> 40-9=24+7
=> 31=31
5(2x+3)=4(x+1)+2
=> 10x+15=(4x+4)+2
=> 10x+15=8x+2
=> 10x-8x=15-2
=> 2x= 13(Am not quite sure)
Sorry as I dont know the ans of this 4m+32.4=-7:6
Rest all pls try to solve it by urself and if u can't solve ask the doubt again and if I see that doubt I will clear that doubt
I HOPE IT HELP U
