solvefor x,7y+8y=12-3x+x

solve for

x, 7 y + 8 y = 12 - 3 x + x

x = - \frac{15 y - 12}{2}

Solution steps

7 y + 8 y = 12 - 3 x + x

Switch sides

12 - 3 x + x = 7 y + 8 y

Add similar elements:

- 3 x + x = - 2 x

12 - 2 x = 7 y + 8 y

Add similar elements:

7 y + 8 y = 15 y

12 - 2 x = 15 y

Move

12

to the right side

- 2 x = 15 y - 12

Divide both sides by

- 2

x = - \frac{15 y - 12}{2}

- 2 c + 56 - 13 c = 32 - 52 c + 2

5 x - 8 = x + 6

2 x - \frac{3 x - 1}{3} = x + \frac{1}{3}

2 = 4 - 2 x

2 (r + 6) = 4 (r + 4)
