If the equation 6x + 5y-2-3rx-2ry + 4R = 0 about X and Y does not contain y term after merging the similar term, the value of R is obtained

If the equation 6x + 5y-2-3rx-2ry + 4R = 0 about X and Y does not contain y term after merging the similar term, the value of R is obtained

∵ 6x + 5y-2-3rx-2ry + 4R = 0, there is no y-term after merging the similar terms, ∵ 5-2r = 0, the solution is r = 2.5
