Y=2x-3<br> y=x+2 system of equations
irina1246 [14]

Answer:

x = 5

y = 7

Step-by-step explanation:

<em>Since they are both equal to </em><em>y</em><em>, we can set them equal to each other.</em>

2x - 3 = x + 2

<em>Combine like terms and isolate the </em><em>x</em><em>.</em>

x = 5

<em>Plug in the x to either equation to get the value of </em><em>y</em><em>.</em>

y = (5) + 2

y = 7
