The old rate of pay is x and the new rate is y then we have:
y = 2x + 7
Y = 21
PART 1: 21 = 2x+7
Subtract 7 from each side:
14 = 2x
Divide both sides by 2:
X = 14 / 2
X = 7
PART 2: The internship pays $7 per hour.
10.
5 multiplied by 2 "5 x 2" = 10

because there variables represent 1 so 1 cant be bigger than one and the other two have real equations
The answer is 19
work :
1-multiply the numbers by a submultiple of 10 to remove the decimal points.

2-
now do the division :

so the answer is 19
note: there is no need to get it back to decimal number unless you multiply just one of the numbers or multiply the numbers with different submultiples of 10
good luck
