Hey only need help with this one problem.
5x+10y-15
thx','

Step-by-step explanation:

Simplifying

5X + -10Y = 15

Solving

5X + -10Y = 15

Solving for variable 'X'.

Move all terms containing X to the left, all other terms to the right.

Add '10Y' to each side of the equation.

5X + -10Y + 10Y = 15 + 10Y

Combine like terms: -10Y + 10Y = 0

5X + 0 = 15 + 10Y

5X = 15 + 10Y

Divide each side by '5'.

X = 3 + 2Y

Simplifying

X = 3 + 2Y

answer: 1 and 3

step-by-step explanation:

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
