Answer:
A. {4,3}
Step-by-step explanation:
x -2y = -2
y = - 3x +15
x - 2(-3x+15) = -2
x +6x - 30 = -2
7x = 28
x = 4
y = - 3x +15 = - 3*4 + 15 = -12 + 15 = 3
{4,3}
Answer:
the numbers next to a variable is a coefficient, for instance in 2x 2 would be the coefficient.
the constants are the numbers without variables next to them, just numbers
like terms are the term that are similar like 2x and 8x or even 5 and 3
lm not exactly sure what they mean when asking for constant terms.

Answer:
Step-by-step explanation:
it depends. if (for example) y=x2 then there are an infinite amount of answers. if there is an equation like: If (variable X)= (variable Y) + 5 and if X=5, what is Y? then there is only one answer. check an algebra book, it can give you a more detailed answer.
