Question

which of these equations is correct when x = -2? choose one option a x + 8 = 5 b 3x - 1 = -10 c 2x - 7 = -11 d -95x = -190

Explanation:

Step1: Test Option A

Substitute $x=-2$: $-2 + 8 = 6
eq 5$

Step2: Test Option B

Substitute $x=-2$: $3(-2) - 1 = -6 - 1 = -7
eq -10$

Step3: Test Option C

Substitute $x=-2$: $2(-2) - 7 = -4 - 7 = -11 = -11$

Step4: Test Option D

Substitute $x=-2$: $-95(-2) = 190
eq -190$

Answer:

C. $2x - 7 = -11$
