solve for x using cross multiplication.\n$\frac{x - 1}{4}=\frac{2x + 4}{5}$\n$x = ?$
Answer
Explanation:
Step1: Cross - multiply
$5(x - 1)=4(2x + 4)$
Step2: Expand both sides
$5x-5 = 8x+16$
Step3: Move x terms to one side
$5x-8x=16 + 5$
Step4: Simplify both sides
$-3x=21$
Step5: Solve for x
$x=\frac{21}{-3}=-7$
Answer:
$-7$
