Answer #1

your second question is worded weird, so ill help with the first one. since you also used over for fractions, then so will I.

first step, you know that you have to make the variable w be by itself so…

you subtract 3 over 7 from both sides of the equation. (both sides of the equal sign)

therefore you are left with w + 3 over 7 - 3 over 7 = negative 5 over 7 - 3 over 7

with me so far? if you dont get it, you wont get the rest

so now w is by itself so now you have to solve

since negative 5 over 7 and 3 over 7 are common fractions you just subtract them

therefore, you get negative 8 over 7

if you dont get it, lemme know
