Given the equation:
3x + 2y = 7
2x + 3y = 7
Find the x-intercept.
Solution:
In order to find the x-intercept of an equation, we equate y to 0, then solve for x.
3x + 2(0) = 7
3x = 7
Divide both sides by 3 in order to determine the value of x.
3x/3 = 7/3
x-intercept= 7/3
2x + 3(0) = 7
2x =7
2x/2 = 7/2
x -intercept = 7/2
Final answer:
x-intercept = 7/3
x-intercept = 7/2
