no x would be 0.5 because two times 0.5 is 1 ( 2x ) and then add 7 equals 8 ( plus seven equals 8 )

X=7

(3, 2)

f(x) = 2x + 8 f(x) = -7 → 2x + 8 = -7 → 2x = -15 → x = -7½ = -7.5

2x + 1 = 82x = 7x = 7/2 = 3.5whew !

no x would be 0.5 because two times 0.5 is 1 ( 2x ) and then add 7 equals 8 ( plus seven equals 8 )

X=7

Sum Numb!

(3, 2)

f(x) = 2x + 8 f(x) = -7 → 2x + 8 = -7 → 2x = -15 → x = -7½ = -7.5

2x + 8 + x = 2x + 15 simplify 2x to both sides since they have the same sign8 + x = 15 subtract 8 to both sidesx = 7

2x + 1 = 82x = 7x = 7/2 = 3.5whew !

6x-8+2x-5 = 7-2x 6x+2x+2x = 7+8+5 10x = 20 x = 20/10 x = 2

8 - 10 + 7 = 5 x = 4

x=1 y=7

The answer is - not are : (1, 7).
