Question

Can someone help plz

Answer 1

A.) 2x - 9x - 30 = -6

Explanation:

hello !

to solve this system of equations, first, we substitute the equation
`y = 3x + 10` to the y variable in the equation
`2x-3y = -6`. Therefore, we get:

`2x - 3(3x+10)=-6`

now, we simplify by multiplying -3 to the variables inside the parenthesis, which, in short, is also called the distributive property. thus, we get:

`2x - 9x - 30 = -6`
