Question

1. solve the equation.

$\frac{2}{7}(x + 4)=6$

1. at a bargain store, tanya bought 3 items that each cost the same amount, but each was $2.25 less than the items that cost the same amount, but each was $2.25 less than the items t paid the same amount of money. what was the total amount that

write an equation. let x represent the cost of one of tanyas item

Explanation:

Step1: Isolate the term with x

Multiply both sides by $\frac{7}{2}$ to get $x + 4=6\times\frac{7}{2}$.

Step2: Calculate the right - hand side

$6\times\frac{7}{2}=\frac{42}{2}=21$, so $x + 4 = 21$.

Step3: Solve for x

Subtract 4 from both sides: $x=21 - 4$.

Answer:

$x = 17$
