Answer:
x=0
Step-by-step explanation:
13x-2 = 10x-2
Subtract 10x from each side
13x-10x-2 = 10x-2 -10x
3x-2 = -2
Add 2 for each side
3x-2+2 = -2+2
3x= 0
divide by 3
3x/3 = 0/3
x =0
Answer:
D.) 12
Step-by-step explanation:
16x - 3(4x + 5) = 2x + 9
16x - 12x - 15 = 2x + 9
4x - 2x = 15 + 9
2x = 24
2x/2 = 24/2
x = 12
Check:
16x - 3(4x + 5) = 2x + 9
16(12) - 3(4(12) + 5) = 2(12) + 9
192 - 3(48 + 5) = 2(12) + 9
192 - 3(53) = 24 + 9
192 - 159 = 33
33 = 33
The square root of -48 is 2 because 2x2x2x2x2x2x is not -48
