<u>Step 1: Define</u>
10.5x - 1.9 = 19.1
<u>Step 2: Solve for </u><em><u>x</u></em>
Add 1.9 to both sides: 10.5x = 21 Divide 10.5 on both sides: x = 2
<u>Step 3: Check</u>
<em>Plug in x into the original equation to verify it's a solution.</em>
Substitute in <em>x</em>: 10.5(2) - 1.9 = 19.1 Multiply: 21 - 1.9 = 19.1 Subtract: 19.1 = 19.1 Here we see that 19.1 does indeed equal 19.1.
∴ x = 2 is a solution to the equation.

Answer: I dont know if im right for sure but the answer should be 4
Step-by-step explanation
8 goes into 2 4 times (8 divided by 2 = 4)
Each child ate 2 pieces (4-2=2)
so therefore for it to be 2 pieces left over there were 4 kids I think.
(-1.5,3) Y=3 which is up 3 and a horizontal line and 2x+y=0 can be written as y=-2x so in order to get -1.5 you have to make y=3 cause y=3 and when you do that it should look like 3/-2=-2/-2x so x=-1.5
Answer:
y = 7
Step-by-step explanation:
5(3y - 13) = 6y - 2
5*3y + 5*-13 = 6y - 2
15y - 65 = 6y - 2
15y - 6y = 65 - 2
9y = 63
y = 63/9
y = 7
Check:
5((3*7)-13) = 6*7 - 2
5(21-13) = 42 - 2
5*8 = 40
3(n - 5) = 24Answer: x = 13
