Linear Equations

The sum of digits of a two-digit number is 12. The number obtained by interchanging the digits exceeds the original number by 18. Find the number.

Find the point of intersection of x = 3 and y = -2.

Solve for x: 7(x - 2) = 0

If 3x + 12 = 0, find x.

Solve: x/10 = 0.5

If y = 2x and x = 5, find y.

Solve for m: m + 4 = -6

Find x: 100x = 10
