Question

9x-2y=-6 5x+4y=12
solve by substitution ​

Answer 1

x = 0

y = 3

Explanation:

Step 1: Write systems of equations

9x - 2y = -6

5x + 4y = 12

Step 2: Rewrite 1st equation

9x = 2y - 6

x = 2/9y - 2/3

Step 3: Substitute

5(2/9y - 2/3) + 4y = 12

Step 4: Solve for y

10/9y - 10/3 + 4y = 12

46/9y - 10/3 = 12

46/9y = 46/3

y = 3

Step 5: Plug in y to find x

5x + 4(3) = 12

5x + 12 = 12

5x = 0

x = 0
