Can anyone me ? i need someone to check my answer what are the 3 different ways for solving systems of equations and when would you use each one?

Elimination: use when x and y terms correspond correctly and can be multiplied/manipulates in a convenient way
substitution: use when either y or x term is isolated and put in values according to the given
graphing: use if you would like a visual for the systems and to find to coordinates, aka the x and y values.
hope this helps x

B. because the 7 represents "seven times", x represents "a number", 12 represents "plus twelve", and -4 represents "minus four"
