Solve the inequality \$ 5x - 9y le 8x + 3y - 4 \$.
Step: 1 |
|
To isolate the variables on one side, then move the y terms to the left side and the x terms to the right side: \$5x - 8x ≤ 3y + 9y - 4\$ Combine like terms: \$-3x ≤ 12y - 4 \$ |
|
Explanation: |
|
Split variables on each side, then group like terms together for simplification. |
|
Step: 2 |
|
Now, let’s isolate the y terms by moving the x terms to the right side: \$-3x + 4 ≤ 12y\$ Divide both sides of the inequality by 12: \$ (-3/12)x + 4/12 ≤ y \$ Simplify: \$ (-1/4)x + 1/3 ≤ y \$ |
|
Explanation: |
|
Isolate y, simplify, then divide by 12 to yield \$ (-1/4)x + 1/3 ≤ y \$. |
