Answer:
1. [tex]x-3=-15[/tex]
2.[tex]2x=-24[/tex]
3.[tex]2x-3=-27[/tex]
Step-by-step explanation:
Given the following question:
[tex]2x+9=-15[/tex]
To find three equations that have the same solution as the given equation we have to first solve the equation.
[tex]2x+9=-15[/tex]
[tex]9-9=0[/tex]
[tex]-15-9=-24[/tex]
[tex]2x=-24[/tex]
[tex]2x\div2=x[/tex]
[tex]-24\div2=-12[/tex]
[tex]x=-12[/tex]
Equation one:
[tex]x-3=-15[/tex]
[tex]-3+3=0[/tex]
[tex]-15+3=-12[/tex]
[tex]x=-12[/tex]
Equation two:
[tex]2x=-24[/tex]
[tex]2x\div2=x[/tex]
[tex]-24\div2=-12[/tex]
[tex]x=-12[/tex]
Equation three:
[tex]2x-3=-27[/tex]
[tex]-3+3=0[/tex]
[tex]-27+3=-24[/tex]
[tex]-24\div2=-12[/tex]
[tex]x=-12[/tex]
Hope this helps.
