67+x=2400:8 y–143=18*3 c*19=2000–100

To solve each equation, we will isolate the variable on one side.

1. Equation: \(67 + x = \frac{2400}{8}\)

   First, compute \(\frac{2400}{8}\): \[ \frac{2400}{8} = 300 \] Now, rewrite the equation: \[ 67 + x = 300 \] Subtract 67 from both sides: \[ x = 300 - 67 = 233 \]

2. Equation: \(y - 143 = 18 \times 3\)

   First, compute \(18 \times 3\): \[ 18 \times 3 = 54 \] Rewrite the equation: \[ y - 143 = 54 \] Add 143 to both sides: \[ y = 54 + 143 = 197 \]

3. Equation: \(c \times 19 = 2000 - 100\)

   First, compute \(2000 - 100\): \[ 2000 - 100 = 1900 \] Rewrite the equation: \[ c \times 19 = 1900 \] Divide both sides by 19: \[ c = \frac{1900}{19} = 100 \]

Now we have the solutions:

• \(x = 233\)
• \(y = 197\)
• \(c = 100\)
