5.
For each equation, determine if x = 2 is a solution. Explain or show your reasoning.
a.
-2(x – 4) = 4
b.
26
= 13
C.
-3.8x = -7.4
4(x - 1) – 3(x - 2) = -8
d.
A. Yes because -2(2-4) does equals =4 B. Yes because 26/2 does equals = 13 C. No because -3.8(2) equals -7.6 and not -7.4 D. No because 4(2-1)-3(2-2) equals 4 and not -8
