Answer:

x=2.5

Step-by-step explanation:

Solve for x in this systems of equations, we already have two values which equal y so half the work is finished for us.

Starting with the equation:

$x+12=17-x$

Add x to both sides to remove the negative x on the right side of the equation:

$2x+12=17$

Subtract 12 from both sides to remove the 12 on the left side of the equation:

$2x=5$

Divide both sides by 2 to cancel out the x coefficient

$x=2.5$
