Answer:

x=2.5

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
