Solution
The equations you provided seem to have some formatting issues. However, I'm assuming you meant the following system of equations:
- g + h = 14
- 3g - 4h = -14
To solve this system of equations, you can use the method of substitution or elimination. Here's a step-by-step solution using the elimination method:
Step 1: Multiply the first equation by 3 and the second equation by 1 to make the coefficients of g the same in both equations:
3*(g + h) = 314 1(3g - 4h) = 1*(-14)
This gives us:
3g + 3h = 42 3g - 4h = -14
Step 2: Subtract the second equation from the first:
(3g + 3h) - (3g - 4h) = 42 - (-14)
This simplifies to:
7h = 56
Step 3: Solve for h by dividing both sides of the equation by 7:
h = 56 / 7 h = 8
Step 4: Substitute h = 8 into the first original equation:
g + 8 = 14
Step 5: Solve for g:
g = 14 - 8 g = 6
So, the solution to the system of equations is g = 6 and h = 8.
