Step-by-step explanation:
4(2x-7)=8x-28
4(-4x+18)=-16x+72
(8x-28)-(-16x+73)
24x+45
We could use Algebra for this question but it’s quite simile so won’t need it. If Amanda is 25, when we add on 5 years she’ll be 30. Now it says when she’s 30, she will be twice as old as Simone. Implying that Simone will be half of Amanda’s age. In this case 30/2 = 15. So Simone must be 15.
X=-8 is the answer so it would be C
