Question

Is the equation true, false, or open? 5x – 10 = 12x + 3

Which value is x in this solution of the equation: –12 + 4x = –20?


Which ordered pairs are a solution of the equation: y = –3x – 2? (Circle all of the correct ordered pairs [more than one pair may be correct])
(0, –2)
(1, 5)
(5, –35)
(–3, 7)

Answer 1

–12 + 4x = –20
4x = -8
x = -2

y = –3x – 2
check by subbing in the ordered pair in question, I will do (-3,7)

LS = 7
RS = -3(-3) - 2 = 7
LS = RS, so yes, (-3,7) is a solution to your equation

do the others in the same way
