Answer:
I think the last you already have is right. I wasn’t very good at this but I try
Step-by-step explanation:
Answer:
First option: (Substitute)
2x+3 (x+1.5) = 12
3√32x^4z
= 3√(2^5)* x^4 *z
(Square rooting the terms)
= 3*2*2*x*x√2*z
=12x^2√2z
3(2x+8)=8x+46
6x+24=8x+46
-2x+24=46
-2x=22
x=-11
3(2(-11)+8)=8(-11)+46
3(-22+8)=-88+46
3(-14)=-42
-42=-42
Hope I didn't mess up for your sake
