Y/4+−49=−9
y=
this is a two step equation again from vmathlive

Remember you can do anything to an equation as long as you do it to both sides

(y/4)-49=-9
isolate the variable
add 49 to both sides
y/4=40
multiply both sides by 4 to clear fraction
y=160

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
