I suspect this is what you mean, if let me know
2x(3)^2+x(2)^2
2(3)(9)+3(4)
54+12=66
To substitute, solve for one variable and then plug it into the other equation you have. In this problem, y is already solved for on the top equation (y=x+2), so you just stuff it into the second equation.
y = x + 2
3y = 4x - 2
3(x + 2) = 4x - 2
3x + 6 = 4x - 2
-x = -8
x = 8
y = x + 2 = 8 + 2 = 10
solution:
x = 8
y = 10
hope this helps!! :)

Answer:
20) 7/16 = 0.4375
21) 1/6 = 1.6 repeating
22) 2 4/5 = 2.8
23) 98 2/3 = 98.6 repeating
24) 0.8 = 4/5
25) 26 1/5
26) 72.1 repeating = 72 1/9
27) 0.505 = 101/200
Explanation:
To convert fraction into decimal, divide the numerator by the denominator and that's your answer. For example:
7 ÷ 16 = 0.4375.
To convert a decimal into a fraction, place the number after the decimal point over the number place it's in. For example: If you look at 0.8 , 8 is in the tenths place, so you place it over 10 like this 8/10, and then you simplify. Half of 8 is 4 , and half of 10 is 5, so you'd have 4/5.
For #27, since 505 in 0.505 , is in the thousandths place, you'd put it over 1,000 like this 505/1000 and then you simplify. <u>Look</u><u> </u><u>at</u><u> </u><u>image</u><u> </u><u>above</u><u> </u><u>to</u><u> </u><u>learn</u><u> </u><u>how</u><u> </u><u>to</u><u> </u><u>simplify</u><u> </u><u>5</u><u>0</u><u>5</u><u>/</u><u>1</u><u>0</u><u>0</u><u>0</u>.⤴⤴⤴
