Answer:
x=-5
Step-by-step explanation:
- Solve the bottom equation for y
- You would just add 5x to both sides so that it cancels out leaving y = 5x + 34
2. Put your new y equation into your top equation (4x + 2y = -2). It should now be 4x + 2(5x + 34) = -2.
3. Then, solve for x.
- Distribute the 2 into 5x and 34. (Should now be 4x + 10x + 68 = -2).
- Add the like terms - 4x and 10x. (Now 14x + 68 = -2).
- Subtract 68 from both sides to get 14x on its own. (Now 14x = -70).
- Divide both sides by positive 14 to get x on its own and the answer as to what x represents. (x = -5).
Hope that helps!
Add them together and equal them to 90 degree. 2x - 12 = 90, 2x = 112, x = 56
