Answer:
A.) 2x - 9x - 30 = -6
Step-by-step explanation:
hello !
to solve this system of equations, first, we substitute the equation [tex]y = 3x + 10[/tex] to the y variable in the equation [tex]2x-3y = -6[/tex]. Therefore, we get:
[tex]2x - 3(3x+10)=-6[/tex]
now, we simplify by multiplying -3 to the variables inside the parenthesis, which, in short, is also called the distributive property. thus, we get:
[tex]2x - 9x - 30 = -6[/tex]
