2/3 (y plus 57) equals 178

210

Step-by-step explanation:

first you do distributive property, so 2/3 times y and 2/3 times 57

Then your new equation will be 2/3y + 114/3=178

Then you simplify 114/3 which mean you divide 114 by 3 and that will be 38

Then you subtract 38 from 178

Your new equation should be 2/3y=140

Then you divide 2/3 over 140 and you will get 210. To do that you a process called keep, change flip, where you keep the number of 140, you change the sign to mtiplication and you flip the numbers to 3/2, then you multiply 140 times 3 then you divide it by 2 and you should get 210

Step-by-step explanation:

2/3 (y+57) = 178

2y/3 + 2*57/3 = 178

2y/3 + 114/3 = 178

2y/3+38=178

2y/3=178-38=140

2y/3=140

y=140*3/2=210
