Math Problem Statement

solve the formula 4x+3y=7

Solution

To solve the equation 4x+3y=74x + 3y = 7 for one variable in terms of the other, follow these steps:

Solve for xx in terms of yy:

  1. Isolate 4x4x on one side by subtracting 3y3y from both sides:

4x=73y4x = 7 - 3y

  1. Solve for xx by dividing both sides by 4:

x=73y4x = \frac{7 - 3y}{4}

Solve for yy in terms of xx:

  1. Isolate 3y3y on one side by subtracting 4x4x from both sides:

3y=74x3y = 7 - 4x

  1. Solve for yy by dividing both sides by 3:

y=74x3y = \frac{7 - 4x}{3}

So, the solutions are:

  • x=73y4x = \frac{7 - 3y}{4}
  • y=74x3y = \frac{7 - 4x}{3}
