Explain, in your own words, the steps necessary to solve a system of equations using the substitution method.

Step-by-step explanation:

you solve for one of the variable in terms of the 2nd variable in one equation. then you substitute that equation for the variable in the second equation. since it now only has one variable you should be able to solve for the variable.

b

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
