easy!!!! 5-7y=33
-7y=33-5
-7y=28
-7/-7=1(y)=y so...
y=28/-7 ( have to divide -7 in both sides)
y=-4 ur done!!!!
PS: to check just substituted-4 for Y it has to be the same answer in both sides pf the = sign.

y is negative 4 you guys are mixing up the negative sign. the answer is negative 4. if it were 4 then it would be 5 - 7x4 which is 5 minus 28. so that would me negative 23 is equal to 33.

continuously, u are required to locate the variable ( what the letter signify). subsequently make the letter stand on my own on one fringe of the equation or question, and deliver all the different numbers to the different ingredient. however the rule of thumb is this; if is the quantity to be despatched is including(+) whilst it crosses the equivalent sign(=) to the different ingredient it replace into minus or unfavourable (-) and vice versa and if dividing then it turns into multiplication or multiply and vice versa. in this actual situations we would desire to locate Y and because 5 is dividing we deliver it to the different ingredient. Y = 12*5 = 60. subsequently answer is 60.

Subtract 5 from both sides.
Divide both sides by -7.
