3x + 1/5y = 7

To solve for a variable, you have to isolate the variable that you want to solve. In this case, we want to solve for "x," so we must isolate "x."

So, subtract 1/5y from both sides.

3x = -1/5y + 7

Then, divide both sides by 3.

3x ÷ 3 = (-1/5y + 7) ÷ 3

Simplify.

x = -1/15y + 7/3

~Hope I helped!~

one taco supreme and two pan pizzas provide 3850 calories. Two taco supremes and one pan pizza provide 3770 calories . Find the
Sedaia [141]

Answer:

Taco supreme is 1230 calories

Pan pizza is 1310 calories

Step-by-step explanation:

Let's denote taco supreme as T and pan pizza az P. We have:

T+2*P = 3850 and 2*T + P = 3770

If we add the equations we get 3*T+3*P = 7620

3*(T+P) = 7620

T+P = 2540 => we can use T=2540-P

Back to one of the first equations we get 2540-P+2*P=3850

P=3850-2540= 1310

=>T= 2540-1310= 1230

Solve for t<br><br> 4/3 = t/7
Mumz [18]

Answer:

\frac{28}{3}=t

Step-by-step explanation:

\frac{4}{3}=\frac{t}{7}

Use cross products to simplify the equation. Multiply the denominator of the second fraction by the numerator of the first fraction, and the denominator of the first fraction by the numerator of the second,

(4)(7) = (3)(t)

Simplify,

28=3t

Inverse operations,

\frac{28}{3}=t
