Question

Solve for the variable
X-1 over 8 = 3 over 4

Answer 1

Try cross multiplying.

Answer 2

\( \color{Black}{\Rightarrow 4(x - 1) = 8\cdot 3 }\)

Answer 3

Can you manage it now?

Answer 4

no

Answer 5

Try distributing using the distributive property - \(a(b \pm c ) = ab \pm ac\)

Answer 6

\( \color{Black}{\Rightarrow 4x - 4 = 24}\)

Isolate \(x\).

Answer 7

X-1/8=3/4
4(X-1)=3*8
4X-4=24
4X=24+4
4X=28
X=28/4
X=7
