Best ResponseYou've already chosen the best response.13u + v = 7 3u = v + 23 **** See **** below for graphical solution **** Rearrange the second equation: 3u  v = 23 3u + v = 7 6u = 30 (add the two equations) u = 5 v = 7  3(5) = 8 solution is u = 5, v = 8 (the point (5,8) on the uv plane) since there is one solution, the two lines intersect in one point, and the system is consistent and independent ******* Graphical solution approach ******* To graph the lines (in the uv planeu= horizontal axis): 3u + v = 7 (0,7) is vintercept (7/3,0) is the uintercept) 3u = v + 23 (0,23) is the vintercept (23/3,0) is the uintercept connect the two intercepts for each line, and find the point of intersection or, converting to v = mu + b form: v = 3u + 7 (slope 3, vintercept 7) v = 3u  23 (slope 3, vintercept 23) draw lines this way and find intersection which will be (5,8)

Best ResponseYou've already chosen the best response.1Simplifying 2x + 2y + 3z = 6 Solving 2x + 2y + 3z = 6 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2y' to each side of the equation. 2x + 2y + 2y + 3z = 6 + 2y Combine like terms: 2y + 2y = 0 2x + 0 + 3z = 6 + 2y 2x + 3z = 6 + 2y Add '3z' to each side of the equation. 2x + 3z + 3z = 6 + 2y + 3z Combine like terms: 3z + 3z = 0 2x + 0 = 6 + 2y + 3z 2x = 6 + 2y + 3z Divide each side by '2'. x = 3 + 1y + 1.5z Simplifying x = 3 + 1y + 1.5z
