Solve for X &amp;Y <br>2x-3y=8 <br>2x+3y=4
aleksandrvk [35]
1. Since 2x2x does not contain the variable to solve for, move it to the right side of the equation by subtracting 2x2x from both sides.−3y=−2x+8-3y=-2x+8Divide each term by −3-3 and simplify.
Divide each term in −3y=−2x+8-3y=-2x+8 by −3-3.<span><span>−3y−3=−2x−3+8−3</span><span>-3y-3=-2x-3+8-3</span></span>Simplify the left side of the equation by canceling the common factors.
<span><span>y=−<span>2x−3</span>+<span>8−3</span></span><span>y=-<span>2x-3</span>+<span>8-3</span></span></span>Simplify each term.
