Question

A set of equations is given below:

Equation H: y = –x + 2
Equation J: y = 3x – 4

Which of the following steps can be used to find the solution to the set of equations? (4 points)



–x = 3x – 4
–x +2 = 3x
–x + 2 = 3x – 4
–x + 1 = 3x + 2

Answer 1

will give medal

Answer 2

hint: substitution

Answer 3

ya ik but i dnt understand that

Answer 4

hint: \(\large {
\begin{cases}
{\color{blue}{ y}} = –x + 2\\
{\color{blue}{ y}} = 3x – 4
\end{cases}\qquad {\color{blue}{ y}} ={\color{blue}{ y}}
}\)

Answer 5

we know y = 3x - 4 since it's given

Answer 6

replace y with what it is also equal to

Answer 7

for example

y = 2x
y = 3x

we can say 2x = 3x or 3x = 2x since the 2x and 3x are both equal to y, so they have to be equal to each other

Answer 8

so you slve 4 y

Answer 9
