Ответ:
12x = 12
x = 1
Substitute
5(1) -3y =23
5 - 3y = 23
-3y = 18
y = -6
x=1 and y=-6
Ответ:
Sample Write the equation using slope and y-intercept in slope-intercept form, y = –275x + 3500. Then, substitute the x and y values of the point into the equation, 1850 = –275(6) + 3500. Simplify to see if both sides are equivalent. Yes, the instructor is correct because both sides are equivalent.
