A 2x - 7 = -12x - 7 = -1
B 3x + 8 = 13x + 8 = 1
C 12x + 8 = 101 2 x + 8 = 10
D 12(2x - 6) = -61 2 (2x - 6) = -6
E 12(4x - 8) = -2
just pick one
To select the correct equation that has the solution x = -3, we can test each equation by substituting x with -3.
Let's go through each option:
A) 2x - 7 = -1
Substitute x with -3:
2(-3) - 7 = -1
-6 - 7 ≠ -1
So, this equation does not have the solution x = -3.
B) 3x + 8 = 1
Substitute x with -3:
3(-3) + 8 = 1
-9 + 8 ≠ 1
So, this equation does not have the solution x = -3.
C) 12x + 8 = 10
Substitute x with -3:
12(-3) + 8 = 10
-36 + 8 ≠ 10
So, this equation does not have the solution x = -3.
D) 12(2x - 6) = -6
Substitute x with -3:
12(2(-3) - 6) = -6
12(-6 - 6) = -6
12(-12) = -6
-144 ≠ -6
So, this equation does not have the solution x = -3.
E) 12(4x - 8) = -2
Substitute x with -3:
12(4(-3) - 8) = -2
12(-12 - 8) = -2
12(-20) = -2
-240 ≠ -2
So, this equation does not have the solution x = -3.
It looks like none of the options have the solution x = -3 when checked against the given equations. There might have been a typo in the options provided. Please double-check the equations and options.
