Question

how do you solve 10x -1 +2y =15

Answer 1

Your answer is $x = (8-y) / 5$

Here's how:

Step 1: Add 1 to both sides. 10x + 2y = 15 + 1

Step 2: Simplify 15 + 1 to 16. 10x + 2y = 16

Step 3: Factor are the common term 2. 2(5x + y) = 16

Step 4: Divide both sides by 2. 5x + y = 16/2

Step 5: Simplify 16/2 to 8. 5x + y = 8

Step 6: Subtract y from both sides. 5x = 8 - y

Step 7: Divide both sides by y. x = (8-y) / 5

This answer is if you want to solve for x! If you want to solve for y, let me know and I'll change my answer! Have a nice night!
