Question

Solve the following system graphically using technology, verify the solution

Y=36x - 75
Y= -49x - 66

Answer 1

y = 36x - 75
y = -49x - 66

36x - 75 = -49x - 66
+ 49x + 49x
85x - 75 = -66
+ 75 + 75
85x = 9
85 85
x = ⁹/₈₅
y = 36x - 75
y = 36(⁹/₈₅) - 75
y = 3⁶⁹/₈₅ - 75
y = -71¹⁶/₈₅
(x, y) = (⁹/₈₅, -71¹⁶/₈₅)
