2x + 5y = 26....multiply by 3
3x + 4y = 26...multiply by -2
------------------
6x + 15y = 78 (result of multiplying by 3)
-6x - 8y = - 52 (result of multiplying by -2)
-----------------add
7y = 26
y = 26/7 (or 3 5/7)
2x + 5y = 26
2x + 5(26/7) = 26
2x + 130/7 = 26
2x = 26 - 130/7
2x = 182/7 - 130/7
2x = 52/7
x = 52/7 * 1/2
x = 52/14 which reduces to 26/7 (or 1 5/7)
solution is : (26/7, 26/7)
Answer:
x-intercept = 30/6 = 5
y-intercept = 30/5 = 6/1 = 6.00000
Step-by-step explanation:
calculate the Y-intercept:
Notice that when x = 0 the value of y is 6/1 so this line "cuts" the y axis at y=6.00000
y-intercept = 30/5 = 6/1 = 6.00000
Calculate the X-Intercept :
When y = 0 the value of x is 5/1 Our line therefore "cuts" the x axis at x= 5.00000
x-intercept = 30/6 = 5
