Find the values of x and y.

x = 10

y = 20

Step-by-step explanation:

Solve for x: 7x + 90 +20 = 180

7x = 70

x = 10

Solve for y: 5x + 2y add up to 90 degrees

5 * 10 + 2y = 90

2y = 40

y = 20

answer: you need the equation in the question so i can answer it

step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
