Question

Solve the following equations and check your results.
1) x = 4/5 ( x + 10 )
2) 2x/3 + 1 = 7x/15 + 3
3) 2y + 5/3 = 26/3 - y

Answer 1

Answer:

1. x=4/5x+8

x=-8

2. 2x/3+1 = 7x/15+3

x=10

3.2y+5/3 = 26/3-y

y=7/3

Answer 2

You'll get an equation in x . Solve this, and you have the x -coordinate of the intersection. Then plug in x to either equation to find the corresponding y -coordinate.
