Answer 1

Answer:

$\frac{3}{2}$x + 2y - 3.5

Step-by-step explanation:

Because the only operation to be used is addition, the parentheses can be taken away:

($\frac{7}{4}$x - 5) + (2y - 3.5) + (-$\frac{1}{4}$x + 5)

$\frac{7}{4}$x - 5 + 2y - 3.5 + -$\frac{1}{4}$x + 5

Addition of negative numbers is subtraction:

$\frac{7}{4}$x - 5 + 2y - 3.5 + -$\frac{1}{4}$x + 5

$\frac{7}{4}$x - 5 + 2y - 3.5 - $\frac{1}{4}$x + 5

Combine like terms to find the furthest simplification of the equation:

$\frac{7}{4}$x - 5 + 2y - 3.5 - $\frac{1}{4}$x + 5

$\frac{6}{4}$x - 5 + 2y - 3.5 + 5

$\frac{6}{4}$x + 2y - 3.5

Finally, simplify the coefficient of x:

$\frac{6}{4}$x + 2y - 3.5

$\frac{3}{2}$x + 2y - 3.5

($\frac{7}{4}$x - 5) + (2y - 3.5) + (-$\frac{1}{4}$x + 5) = $\frac{3}{2}$x + 2y - 3.5
