Solve using substitution:<br> 2x - 3y = -1<br> y = x - 1
denis-greek [22]

<em>Answer:</em>

<em>x=4 y=3</em>

<em>Step-by-step explanation:</em>

<em>rewrite the equations- y=x-1 2x-3y=-1</em>

<em>solve y=x-1 for y</em>

<em>y=x-1</em>

<em>y=4-1</em>

<em>y=3</em>

iris [78.8K]

Answer: C, D and E

Step-by-step explanation: I'm a high school student and my teacher just went over this exact problem today. Here's somewhat how he explained it.
